Application

Biotin protein labeling kit has been used to produce biotinylated denatured bovine serum albumin (d-BSA) for coating cadmium telluride (CdTe) quantum dot (QD) conjugates.The kit is suitable for the labeling of proteins with biotin for immunochemistry, immunoblotting, and ELISA.

General description

For labeling of proteins with biotin.Free amino acids of the protein to be labeled react with D-biotinoyl-ε-aminocaproic acid-N-hydroxy-succinimide ester (biotin-7-NHS) by forming a stable amino bond. Non reacted biotin-7-NHS is separated on a Sephadex G-25 column.

Other Notes

For life science research only. Not for use in diagnostic procedures.

Packaging

1 kit containing 5 components.

Preparation Note

Working solution: Preparation of the solutions Blocking solution: Dissolve the contents of the bottle blocking reagent (green screw cap) in 300 ml double-distilled water. PBS solution: Dissolve the contents of the bottle PBS (blue screw cap) in 1 I double-distilled water. Biotin-7-NHS solution: The solution should be freshly prepared before labeling. Add to the contents of the reaction vial which includes biotin-7-NHS 250 µI DMSO and vortex the solution several times. The resulting concentration of the biotin-7-NHS solution is 20 mg/ml. For the labeling mix, the volume of the biotin-7-NHS solution should not exceed 5% of the total reaction volume (e.g., add maximal 50 µl biotin-7-NHS solution to 1 ml protein solution).
