ALS ELISA Kit

Storage Instruction:Store the kit at 4°C.
Description:
Acid-labile subunit (ALS) is a GH dependent protein which is produced in the liver as a 578 amino acid peptide with a predicted molecular weight of 63.3 kDa. IGFs in human serum are mostly confined to a ~150 KDa GH-dependent ternary protein complex consisting of IGFBP-3, a molecule of IGF-I or IGF-II, and this unique acid-labile subunit (ALS) . The first description of ALS was based on the observation that acidification would result in dissociation of the 150 KDa complex into acid-stable IGF (~7.5 KDa) and IGFBP-3 (~50 KDa) components while neutralization of the acidified sample would no longer support formation of the 150 KDa complex .
