Overview

Pyridoxal-5’-phosphate monohydrate is a vitamin B6 metabolite that can modify lysyl and valyl residues in proteins. It has the ability to inhibit purinergic receptors and intracellular influx of Ca2+. Pyridoxal-5’-phosphate monohydrate can modify peptides and suppress their precursor ionization efficiency. Research shows that pyridoxal-5'-phosphate-dependent enzymes can be inhibited by cycloserine.
A vitamin B6 metabolite that can modify lysyl and valyl residues in proteins.

Note

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
