Alpha-1-B glycoprotein is a 54.3kD protein in humans that is encoded by the A1BG gene. The protein encoded by this gene is a plasma glycoprotein of unknown function. The protein shows sequence similarity to the variable regions of some immunoglobulin supergene family member proteins. Patients who have pancreatic ductal adenocarcinoma show an overexpression of A1BG in pancreatic juice. Sample Type: Cell lysates, cell culture supernates, serum, plasma (Heparin or EDTA). Intended Use: Sandwich High Sensitivity BioAssay? ELISA kit for Quantitative Detection of Human A1BG/alpha 1B-Glycoprotein. Sensitivity: <10pg/ml Range: 31.2pg/ml-2000pg/ml Specificity: Recognizes natural and recombinant Human A1BG/alpha 1B-Glycoprotein. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Human A1BG/alpha 1B-Glycoprotein BioAssay? ELISA Kit was based on standard sandwich enzyme- linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for A1B
