Hydrazide Gel

Description:

Hydrazide Gel is a high efficiency glycoprotein binding medium, which will bind oxidized sugar molecules in the glycosyl groups of Anti-bodies and does not bind to amino acids. This important function makes it specific to immunoglobulins where the gycosylated area is distinctly located away from the hper-variable binding region. By using Hydrazide gel to exploit these antibodies may be linked to a solid phase support via the oxidized glycosyl groups. Thus preserving the antibody integrity, which no other linking method can guarantee. The method employs the oxidation of sugar molecules with sodium meta-periodate which converts vicinal pairs of hydroxyl groups to aldehydes, (-CHO), it is these which bind hydrazide agarose.
