Application Homobifunctional cross-linking reagent specific for aldehydes resulting in relatively stable hydrazone linkages. Typically, used in the linking of glycoproteins, such as antibodies, in a site specific fashion following periodate oxidation. Oxidation and coupling may conveniently be performed at pH 5.0 due to the low pKa of the hydrazide which avoids competition by primary amines. Other Notes Note that the hydrazone bond may be stabilized by selective reduction using, for example, sodium cyanoborohydride. 包装 25, 100 g in poly bottle |
