Product Description
NeutrAvidin Protein is a specially-prepared form of avidin that decreases background in biotin-binding. Features include: • Near-neutral isoelectric point—pI = 6.3, more neutral than native avidin • Nearly devoid of glycosylation—decreased possibility of lectin binding compared to native avidin • No RYD recognition sequence—no known off-target binding domains like streptavidin • Affordable—significantly less expensive than streptavidin NeutrAvidin Protein is deglycosylated native avidin from egg whites. Removal of the excess carbohydrate by an exclusive process yields a protein with a more neutral isoelectric point and less nonspecific binding properties. Purified NeutrAvidin Protein provides exceptional performance in western blot, ELISA, and IHC applications that require biotin-binding probes. Assay specificity, sensitivity, and signal-to-noise ratios with NeutrAvidin Protein are generally equivalent or better than with the significantly more expensive streptavidin. Avidin is a glycoprotein found in the egg white and tissues of birds, reptiles, and amphibia. The biotin-binding protein contains four identical subunits having a combined mass of 67,000-68,000 daltons. Removing the glycosylation from avidin yields NeutrAvidin Protein with a mass of 60,000 daltons. Carbohydrate-based lectin binding is reduced to undetectable levels, yet biotin-binding affinity is retained. NeutrAvidin Protein offers the advantages of a neutral pI to minimize nonspecific adsorption, along with lysine residues that remain available for derivatization or other customized conjugation. NeutrAvidin Protein yields the lowest nonspecific binding among the known biotin-binding proteins. The specific activity for biotin binding is approximately 14 µg/mg of protein, which is near the theoretical maximum activity.

NeutrAvidin Protein (PE) (rp188520) - Flow Cytometry Flow cytometry analysis of CD45 expression by Jurkat cells (red) compared to an isotype control (blue). Cells were stained with CD45 Mouse mAb (Biotin) (Ab185413) at 0.1μg/test for 1 hour at 4°C. Then incubated with NeutrAvidin Protein (PE) (rp188520) at 0.3μg/test for 30 minutes at 4°C in the dark. Blue - Mouse IgG Isotype Control Antibody (Biotin) (Ab180306). Black - Unlabelled control, cells without incubation with primary antibody.
