Invitrogen™ NeutrAvidin Protein, DyLight™ 650

Description

• NeutrAvidin Protein, DyLight 650 conjugate, 84607, from Invitrogen., 84607, from Invitrogen
• Species Reactivity: ; Applications: Immunofluorescence
• 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 14ug/mg of protein, which is near the theoretical maximum activity.
