Lightning-Link Alkaline Phosphatase Labeling Kit

Lightning-Link™
Lightning-Link is the easiest and quickest method available for making antibody (protein) conjugates, requiring just 30 seconds hands-on time. The antibody is covalently bonded to the label in a directional and controlled process at near-neutral pH.

Alkaline Phosphatase
Alkaline phosphatase (AP) is a hydrolyase enzyme that is frequently conjugated to antibodies for use in immunoassays. AP has a lower catalytic rate than HRP, but has greater stability and maintains linear reaction kinetics for much longer. PNPP is a popular colorimetric substrate for AP; the product of the reaction, p-nitrophenol, can be read at 405nM. Fluorogenic substrates (e.g. 4-methylumbelliferyl phosphate; MUP) may also be employed.
