Enzyme immobilisation reagent.
Basic Description Specifications & Purity ≥99% (HPLC) Biochemical and Physiological Mechanisms Reagent for enzyme immobilisation on fibroin by photo-crosslinking; water-soluble over a wide pH range. Storage Temp Store at 2-8°C Shipped In Wet ice 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.
