ALADDIN SCIENTIFIC CORPORATION Adipic acid dihydrazideADH, 100g

Homobifunctional cross-linking reagent that is specific for aldehydes resulting in relatively stable hydrazone linkages This is commonly 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 Note that the hydrazone bond may be stabilized by selective reduction using for example sodium cyanoborohydride General descriptionAdipic acid dihydrazide is a homobifunctional cross-linking reagent that is specific for aldehydes This results in relatively stable hydrazone linkages Adipic acid dihydrazide is generally used in the linking of glycoproteins like antibodies in a site-specific fashion following periodate oxidation Oxidation and coupling may be performed at pH 5 0 due to the low pKa of the hydrazide which avoids competition by primary amines

Sigma Aldrich Fine Chemicals Biosciences L Lactic Dehydrogenase fro

Lactic Dehydrogenase (LDH) has a total molecular weight of 140 kDa and is composed of 4 subunits which are designated M subunit (muscle) and H subunit (heart). These subunits may be mixed in any of 5 combinations (M4 M3H1 M2H2 MH3 and H4). Skeletal muscle contains LDH that is predominately M4 with some small amounts of M3H and traces of H2H2. The H and M subunits are quite similar in molecular weight but differ substantially in amino acid composition. Rabbit muscle LDH dissociates into dimeric species (MW ~70 kDa) in acetate-chloride at pH 5.0 the dissociation is reversible. Biochemistry 13 3527-3531 (1974).
