WebDec 31, 1999 · The effect of biotin binding on the thermal stability of streptavidin (STV) and avidin (AVD) was evaluated using differential scanning calorimetry. Biotin binding increases the midpoint of temperature Tm of thermally induced denaturation of STV and AVD in phosphate buffer from 75 and 83 degrees C to 112 and 117 degrees C at full biotin ... WebAlso, the product can react with carbonyl groups (aldehydes or ketones) to form a Schiff base. The Schiff base can be reduced to a secondary amine using sodium cyanoborohydride if additional conjugate stability is necessary.

WebSep 22, 2013 · Streptavidin and its homologs (together referred to as streptavidin) are widely used in molecular science owing to their highly selective and stable interaction with biotin. Other factors also contribute to the popularity of the streptavidin–biotin system, including the stability of the protein and various chemical and enzymatic biotinylation … WebThe biotin–avidin interaction is commonly exploited to detect and/or purify proteins because of the high specificity that these two molecules have for each other. Biotinylation is the process of attaching biotin to proteins and other macromolecules. Biotinylation reagents are available for targeting specific functional groups or residues ... http://www.nanocs.net/Alexa-fluor488-PEG-biotin-3k.htm t shirt design specs
