NHS-LC-biotin (succinimidyl-6-(biotinamindo)hexanoate), also known as NHS-X-biotin is a derivative of D-biotin, a amine-reactive biotinylation agent, that contains a spacer arm off the valeric acid side chain of D-biotin with an NHS ester group at its end. The NHS ester group at the end of NHS-LC-biotin covalently binds to amine groups in proteins and other molecules forming a stable amide linkage and releasing the NHS group. The 6-aminocaproic acid spacer of NHS-LC-biotin greatly increases the length between a covalently modified molecule and the bicyclic biotin rings leading to a better binding potential for avidin or streptavidin probes. NHS-LC-biotin is insoluble in aqueous environments requiring the dissolution of organic solvents prior to the addition to a buffered reaction.

Improvement of an EIA system for basic fibroblast growth factor by use of biotinylated antibody prepared with NHS-LC-biotin.[Pubmed:7714669]
J Clin Lab Anal. 1995;9(2):96-100.
We improved our previously devised enzyme immunoassay (FIA) system for basic fibroblast growth factor (bFGF) using biotinylated antibody prepared with sulfosuccinimidyl-6-(biotinamido)hexanoate (NHS-LC-Biotin, Pierce), a water-soluble biotin analogue, with an extended spacer arm. The discriminatory detection limit of the improved EIA was found to be 5 pg/ml (0.5 pg/assay tube), sixfold more sensitive than that of the previous system. The reproducibility of within- and between-assay series was 5.10-8.61% and 5.99-8.69%, respectively; and recovery of exogenous bFGF from serum was approximately 102%. Employing the improved EIA system, we investigated by chromatofocusing chromatography the isoelectric points of two immunoreactive bFGFs (high-molecular-weight bFGF-like immunoreactive substance, designated as HMW-bFGF-LI and 16-kd bFGF-LI, having the same molecular weight as recombinant bFGF) detected in serum from a breast cancer patient. As a result, the pI value of HMW-bFGF-LI was estimated to be 7.13, and that of 16 kd bFGF-LI, 9.58.
