Ready-to-use ELISA kits are available for the detection of PKBP1L, an alias of the protein, FKBP prolyl isomerase 1B. The official gene symbol is FKBP1B. The protein, with a mass of 11.8 kDa and length of 108 residues, is reported to be cytoplasmic. It is a member of the FKBP-type PPIase family, FKBP1 subfamily and may be known by other names, including: FKBP-12.6, FK506-binding protein 1B, FK506 binding protein 1B 12.6 kDa, 12.6 kDa FKBP, 12.6 kDa FK506-binding protein, and peptidyl-prolyl cis-trans isomerase FKBP1B, and PPIase FKBP1B.
