Lispro Insulin RIA Kit

This kit measures lispro insulin (Humalog©) in serum, plasma, or other biological fluids without crossreactivity to native human insulin or proinsulin. Lispro insulin is a synthetic human insulin analog with inverted B-chain amino acids in positions 28 (proline) and 29 (lysine). The kit includes all components (standards, matrix, antibody, tracer, quality controls, precipitating reagent and buffers) necessary to complete a RIA.

ASSAY CONDITIONS: Overnight, equilibrium incubation at room temperature. Sample volume <100 µl serum, plasma, or tissue culture media.
