There are a variety of websites that offer peptides for sale. Those looking for peptides to be used for research purposes should take their time in investigating these websites to determine whether the chemicals they have purchased will be suitable for their needs. It is much easier to develop a relationship with one website that you can rely on every time you require a new shipment rather than having to constantly search for new websites to shop from.

Many people purchasing research peptides focus on finding the peptide they require at a low price, but you will need to do further research to determine whether or not a peptide is suitable for use in laboratory conditions. In many cases, an extremely inexpensive peptide will not be suitable for your needs and will require additional work before it can be used to provide accurate results in your research.

Investigating Research Peptides

If you are looking into peptides to be used in research, you will need to ensure that you will be able to gain accurate results.

• Pay close attention to the application size noted on each peptide. This will help you determine what type of animal test subject the peptide is intended to be used on. You may need to adjust doses if you will be using less common test subjects such as swine or birds.
• Some peptides are sold at high concentrations. Note any information about how the peptides should be diluted and whether or not the necessary chemicals to prepare these peptides for research are included in your kit.

Most peptide suppliers provide sterile versions of these chemicals for research use. This should be specified in the product description. If the peptide is not listed as a sterile substance, then it is not intended for use in animal research subjects. Instead, it should be applied to artificial tissues or at the cellular level.

Notes about Shipping and Storage

A peptide website should provide any necessary information regarding how to store your product to ensure maximum stability.

• Any research quality peptides should be shipped in sterile conditions.
• Most peptides can be stored and transported at room temperature for a short period of time, but you will need to keep your peptides frozen if you plan to use them for longer periods of time. Specific information regarding the appropriate storage temperatures for individual chemicals should be listed on the sale page.

Most research-grade peptides have a strict expiration date that will need to be adhered to. After this point, the stability of the peptide cannot be guaranteed, which may alter the results of your research. This expiration date will be listed for those which are kept frozen.

A high quality peptide supplier will be happy to answer any questions you have about the product you are interested in purchasing. If any information is missing from the website, you can send an email to the listed supplier, to learn more about the best way to make use of this product.

Thymosin (also known as tb500) is a code for a synthesized protein TMSB4X that is encoded in the human gene code. This protein is made up of 43 amino acids that help to encode actin sequestering proteins that play a role in cell differentiation, proliferation and migration. The natural form of this protein escapes X inactivation which means it has a homolog on the Y chromosome.

A number of past and present clinical trials have worked to determine the functions of thymosin, to better understand how synthesized versions of this chemical could be used in future research or medical applications. Some research has indicated that applying thymosin after a heart attack could help the body reactivate the cardiac progenitor cells which would help to repair the heart tissue that had been damaged.

However, the potential side effects or risks of applying thymosin to human test subjects are still being researched.

Roles of Thymosin in a Natural Setting

Research hopes to mimic the effects of thymosin beta 4 so it will mimic the effects of the natural protein that is found in humans.

• Research has determined that applying thymosin beta 4 to animal test subjects promotes the formation of blood vessels, migration of cells, survival of certain cells, maturation of stem cells, and lowering the animal’s bodily production of pro-inflammatory cytokines.

• Trials are focusing on finding uses for thymosin beta 4 that take advantage of these properties. Investigations into applying thymosin to wounds of the cornea, skin and heart are ongoing with animal test subjects.

• Test subjects with male animals have noted that thymosin beta 4 can be detected in the urine, which may help researchers determine the presence and aggressiveness of a prostate tumor.

Research in Glasgow found that applying thymosin beta 4 with sulfoxide increased the peptide’s ability to act as an anti-inflammatory agent in animal tissue. This has been found to lower the symptoms of a bacterial infection and the adhesion of these ‘bacterial to endothelial’ cells.

Biological Activities of Thymosin Beta 4

Repeat proteins of thymosin beta 4 have been found to resemble the monomeric forms that allow it to bind to actin.

• When this sequence was studied on Ciboulot fruit flies, this actin binding filament helped researchers monitor sequestration.

• Further investigations with sea slugs showed that these repeating proteins enhanced the sensory neurons in the pathway of a conditioned stimulous.

Applying the phosphorylation of Csp24, along with thymosin beta 4, was found to mimic the post-translational modifications of several proteins related to the cytoskeleton that helped to contribute to the actin-filament dynamics. This encouraged a response too in these cells which allowed for structural remodeling.

Thymosin is available online in wholesale and individually packaged vials. Applications for each of these chemical packs are designed to work with a specific type of test subjects that will be exposed to this chemical. It is important to read the instructions on this kit to determine the appropriate application size, given the size of the animals being used for research.

TB-500 is a synthesized version of Thymosin Beta 4, a peptide that naturally occurs in all animal cells. The natural version of this chemical is used by the animal’s body to improve differentiated endothelial cells so they can perform specialized functions.

This helps the body to grow new cells and dermal tissue to replace any that have aged or been damaged. Thymosin Beta 4 has also been found to play a role in decreasing inflammation, keratinocyte migration and collagen deposition.

The artificial form of this chemical; TB-500 is being investigated for its roles in regulating Actin. This is a cell building protein that helps to encourage cell movement and structure. There are thousands of similar proteins in each animal cell, but actin makes up approximately 10 percent of these proteins, making it an essential part of the genetic makeup of these cells.

Development and Research

• This structure means that the cell can bind to actin proteins, creating an actin sequestering molecule within eukaryotic cells which will block acting polymerization.

• Compared to the natural chemical, TB-500 has been up-regulated to increase the early blood vessel formation by up to 4-6 times, promoting new blood vessel growth in laboratory settings. Experiments indicate that this could have an application in wound healing or skin and muscle building.

• TB-500 encourages cytoskeleton cell migration when interacting with the actin in the cells in these areas. The specific amino chain binding in this peptide has been shown to produce additional extracellular matrix-degrading enzymes during experiments.

Specifically, TB-500 has been shown to accelerate the migration of endotheilial and keratinocyte cells to create the additional matrix-degrading enzymes necessary for these actions. The 43 amino acids used in this structure are specifically designed to interact with these tissues to trigger a repair response that is different from other similar peptides because it can easily move through the necessary tisseus.

Selecting Proper Peptide Sources

While there are similar peptides on the market, it is important to select a provider that will provide research-grade samples of TB-500.

• The patented makeup of this chemical is very specific. Only order from a certified dealer that is able to offer the specific synthetic peptide that offers the active regions of thymosin beta 4 to ensure accurate results.

Read all instructions before applying the peptide to live subjects. Because TB-500 is intended to migrate through tissue, it can often be applied anywhere on the subject, but it may be necessary to place applications in a similar area to generate repeated results.

Research has indicated that TB-500 can mimic the repair factors of thymosin beta 4 to act as an anti-inflammatory substance. This peptide may also encourage growth factors, endothelial and keratinocyte migration. This peptide has been shown to avoid sticking or binding with the extracellular matrix when applied to animal test subjects.

The peptide also has a low molecular weight which helps applications of TB-500 to travel throughout the tissues, often in longer distances than the natural thymosin beta 4.

Rest assured that you will get the best product available when you buy TB-500 from extreme peptides.
