Applications

Firstly, NHS-biotin was dissolved in DMSO at a concentration of 100 mg/mL, after that using 90% DMSO solution diluted the biotin to a concentration of 20 mg/mL. The biotin solution was sterilized by filtering the solution through 0.2-μm pore nylon syringe filters and the solution was diluted with 6 volumes 0.9% saline solution. Blood was allowed to warm to room temperature prior to labeling with NHS-biotin. To achieve a biotin concentration of 0.04 pg of biotin/RBC(Red Blood Cells), Biotin-DMSO-saline solution was injected into each blood bag and agitated for 30 minutes.

Background

NHS-Biotin (C14H18O5N3S) is N-hydroxysuccinimido biotin. It is the shortest of three similar EZ-Link NHS-Biotin Reagents that enable simple and efficient biotinylation of antibodies, proteins and any other primary amine-containing biomolecules in solution. NHS-Biotin offers researchers the possibility of optimizing labeling and detection experiments where steric hindrance of biotin binding is an important factor. Because it is uncharged and contain simple alkyl-chain spacer arms, NHS-Biotin compound is membrane-permeable and useful for intracellular labeling.

NHS-Biotin is the most popular type of biotinylation reagent. NHS-activated biotins react efficiently with primary amino groups (-NH2) in alkaline buffers to form stable amide bonds. Proteins (e.g., antibodies) typically have several primary amines that are available as targets for labeling, including the side chain of lysine (K) residues and the N-terminus of each polypeptide.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
