Thermo Scientific™ Maleimide Activated NeutrAvidin™ Protein is a specially-prepared form of avidin that decreases background in biotin-binding.

• Near-neutral isoelectric point (pI=6.3), more neutral than native avidin
• Decreased possibility of lectin binding compared to native avidin
• No known off-target binding domains like streptavidin
• 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. Conjugated 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.
