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.

| Biotinylation method [1]: | |
|
Sample |
S. aureus |
|
Preparation method |
Soluble in DMSO or DMF. |
|
Reaction Conditions |
60 mg/ml, room temperature for 1 h. |
|
Applications |
Fixed cell suspensions of S. aureus were diluted to a 2% cell suspension in 0.2 M NaHCO3, pH 8.3. NHS-LC-biotin freshly dissolved in DMSO at a concentration of 60 mg/ml, was added to the cell suspension subsequently. After gentle tumble mixing for 60min at room temperature, the reaction was stopped by removal of excess biotin via gel filtration over a PD-10 column and washed extensively in 0.01 mM Tris-buffered 0.15 M NaCl (TBS). Successful protein biotinylation was examining their reactivity with alkaline phosphatase-conjugated streptavidin（AP-STRAV). AP-STRAV binding was detected as a function of pNPP hydrolysis. |
