85-1436-99　［取扱停止］Lactate Dehydrogenase B, Recombinant (LDHB, LDH-B, L-Lactate dehydrogenase B chain) 3mg　L1011-08

特徴

• A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of lactate and pyruvate. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist. Recombinant LDH-B was produced using LDH-B DNA cloned from cDNA library of chicken heart.
• Biological Activity: ~250 U/mg protein
• Unit Definition:One unit is defined as 1 micromole of NAD+ produced per minute under the assay conditions (25°C, pH 7.5). Both transaminase activities include alpha-hydroxyglutarate dehydrogenase activity.
• Storage and Stability:Store lyophilized powder dessicated at -20°C. Upon reconstitution, product may be stored at 4°C for 2-7 days and at -20°C for long-term storage. Prevent freeze-thaw cycles. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
