Our biochemicals are of very high purity, typically >99%. Chemical purity and quality are determined using a comprehensive range of techniques, including HPLC, chiral HPLC, NMR, microanalysis, optical rotation, TLC, and mass spectrometry. Details are provided on the Certificate of Authenticity that accompanies each product.
Products sold in small quantities may not be readily visible, as they can coat the bottom or walls of the vial. It is therefore important that you ensure that solvent comes into contact with all areas of the vial when stabilizing your product.
It is not unusual for different batches of the same product to vary slightly in appearance and color. However, this will not affect purity or quality as described on the batch specific Certificate of Authenticity and will not affect product performance.
The molecular weight and formula published on our website represent the molecular weight and formula of the product as depicted in the chemical structure displayed on our website. However, molecular weights (and formulae) can vary slightly from batch to batch - due to water composition, or due to a change of salt. These changes will be indicated on the Certificate of Authenticity that accompanies your product. The changes should not affect the biological activity of your product, but it is important that you take them into account when making up solutions. You should therefore always use the batch molecular weight as stated on the Certificate of Authenticity or the vial label.
To help you more easily identify a chemical, we provide CAS registry numbers for our products. CAS registry numbers are unique numerical identifiers for chemical substances. The Chemical Abstracts Service (CAS), a division of the American Chemical Society, assigns these identifiers to every chemical that has been described in the literature. Please note, that whilst these are given as accurately as possible on our website, they may not always reflect the level of hydration or salt of the product supplied.
To assist you in your product selection, we provide a brief summary of the biological properties of our products, together with some suggested reading (references) that you may find useful. Please note, that whilst this information is given as accurately as possible on our website, it may not always reflect the latest findings and is not exhaustive. It is intended as a guide only and we therefore recommend that you carry out your own search of the scientific literature for full details of the product's biological activity.
We are often asked for examples of publications which cite AbMole Biochemicals. We try to provide examples of these with our product data wherever possible. If you or your colleagues publish a paper which cites AbMole Biochemicals as the source of one or more of your materials, please send us the details - and we will send you a free gift!
Stabilization instructions can be found on the Certificate of Authenticity accompanying your product, or on the website. Some products may be difficult to solubilize, and you may find that rapid stirring, warming in a water bath, or sonication of the solution may help.
Solubility is temperature dependent. As such, cooling or freezing solutions may lead to precipitation of the product out of solution. It is therefore important to ensure that your product is completely re-dissolved before use.
Products are for research use only. Not for human use. We do not sell to patients.
