It is important to handle research chemicals in the right manner to extend their shelf life and to maintain their efficacy. This is very true when it comes to research peptides that have a relatively low half life and are highly unstable if not stored properly. You can purchase the required research peptides for all your clinical studies at https://americansciencelabs.com/ the leading online seller of quality research peptides.
Now we list out the steps involved in handling and storing of research peptides.
- It is important that the container should be tightly closed always. Do not leave the container open on your worktable as research peptides are highly volatile.
- Do not store the container in direct sunlight. Though most peptides are stable at 4° C it is advisable to keep them refrigerated. If you are going to use the peptide within a short duration usually 1-2 weeks, then it must be stored at -4° C. however if you intend to use it for a longer duration it must be stored at -80° C.
- Exposing the research peptide to moisture decreases it efficacy. Once you take it out from the cold storage, let it reach room temperature before you use it in your experiments. Only when it has reached room temperature you must open the vial. This reduces the intake of moisture from the atmosphere.
- Peptides are bound to undergo oxidation when exposed to air. Hence it is better if you remove the air from the vial and store the peptide in a vacuum container or replace the air with other non reacting gases such as nitrogen, argon or any other inert gases.
- If you do not know the solubility dosages for a particular peptide you can search online to find the right solubility mixture.
- Repeatedly freezing and thawing peptides reduces their efficacy. If you have to thaw repeatedly then it is better to divide the original quantity into smaller working solutions that you can use individually.
- Generally research peptides are stable for a week and it is better to use peptide solutions once opened within a week. If you wish to use it for a longer duration, it is better that you freeze the remaining solution and thaw it as and when required.
- When you prepare a solution of the peptide it is advisable to prepare a solution with a higher concentration than required. The solution can be made by mixing the research peptide with sterilized distilled water or sterilized acetic acid. Ideally the concentration should at least be higher by 0.1%.
- Remember that shelf life of peptides is limited. Hence it is better to order peptides in small dosages as and when required instead of ordering in bulk.
- It is always better to store research peptides in powder or lyophilized form at -80°C in a refrigerator with uninterrupted power supply. If you have the peptide in the form of a solution, avoid repeated thawing.
These are some of the general guidelines for storing and using research peptides. Also check out if the particular peptide you are using has any other specific methods of handling.
