Cat#:RP-2150H;Product Name:Recombinant Human Avidin Biotin Protein;Synonym:Avidin, AVD, AVID.;Description:Avidin is a basic charged glycoprotein present in the egg white and in some extent in tissues of various animals. Avidin is a homotetrameric protein that contains 4 identical subunits which bind to Biotin with high extent of affinity and specificity consisting of 128 amino acids and has a molecular mass of about 67K Daltons. Avidin-Biotin is a modified form of affinity purified avidin that combines the high affinity specific activity of the native egg white avidin to biotin molecule together with a very low background of the streptavidin produced by the bacteria Streptomyces avidinii.;Bioactivity:Please contact us for detailed information;Formulation:Salt-free lyophilized powder with no preservative added.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:We highly recommended to prepare a 1 mg/ml solution; Reconstitute using cold deionized pyrogen free water and mix gently until powder is completely dissolved.;Storage:Store protein solution at 2-8°C.;
