Q:

I need a TBG ELISA that would work for recombinant TBG in cell culture supernatant. Is this kit suitable for that?

A:
Thanks for your inquiry.
CSB-E09501H
The standard in this kit is CHO-derived recombinant protein. As we are not clear about the expression system and modifications of recombinant TBG, sorry we are not sure if it can be detected out or not. For this case we can only suggest you do a pretest first. We validated natural samples before and they can be detected out.

    11. guanine deletion at position 1711, codon 201 (Asp) in exon 2 (GAC --> AC) led to a frame shift and premature termination at codon 206, causing a short TBG protein of 205 amino acids (AA) compared to 395 AA of the normal TBG. PMID: 17887925
    12. new serpina7 gene variant in three members of the same family results in the replacement of the normal asparagine 233 by isoleucine and, subsequently, in disruption of a glycosylation site PMID: 19415532
    13. The first exon (exon 0) is a short noncoding sequence located 1.62 kilobase pairs (kbp) upstream from exon 1. HNF-1 site (located 65 bp upstream of the TSS) is required for the hepatocyte specific expression of the hTBG gene. PMID: 8232304
