Recombinant Human IGFBP3 Protein

• Cat.No.: IGFBP323022H

Specification

• Species: Human
• Description: This consists of a batch of ampoules (coded 93/560) containing nonglycosylated recombinant DNA-derived insulin-like growth factor binding protein-3 (rhIGFBP-3) expressed in E. coli. In an international collaborative study designed to compare the ampouled preparation of rhIGFBP-3 with local standards, apparent differences were detected in several systems, most of which involved comparisons with glycosylated house standards. However there was broad agreement among a number of participants that the ampoule contents were approximately 3.5g, particularly from those assays which were homologous for E. coli-derived IGFBP-3. Because the range of estimates obtained for the ampoule content of the non-glycosylated material indicated that it would not be suitable to serve as a standard in some immunoassay and bioassay systems, the preparation is intended solely for use as a research reagent.
• Storage: Unopened ampoules should be stored at -20ºC or below.
