Human Putative alpha-1-antitrypsin-related protein (SERPINA2) ELISA Kit

Assay Genie's Sandwich ELISA Kit is designed for the precise detection of human Putative alpha-1-antitrypsin-related protein (SERPINA2) in serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids. The assay detects both natural and recombinant human SERPINA2 and is intended for research use only, supporting studies of protease regulation and inflammation relevant to conditions such as chronic obstructive pulmonary disease (COPD), liver disease, and cancer.

Reported specifications include a detection range of 78-5000 pg/mL and a sensitivity of 38 pg/mL. Precision is given as an intra-assay CV of 6.2% and an inter-assay CV of 8.6%. Linearity at the 1:2 dilution spans 104-115% for serum, 97-107% for EDTA plasma, and 84-94% for Heparin plasma. Recovery averages 101% for serum (range 95-107%) and 103% for plasma (range 97-109%).

SERPINA2 (UniProt P20848), also known by the synonyms Protease inhibitor 1-like, Serpin A2, ARGS, ATR, PIL, and SERPINA2P, is described as a putative serine protease inhibitor localised to the endoplasmic reticulum. Kit components are stored at -20°C or 4°C depending on the reagent.
