This IgG glycoprotein standard was developed for use to be used as a positive control during glycan release and labeling.

Source :This product is purified from human blood. Human IgG glycoprotein standard contains a mixture of gamma-type antibodies.

Molecular Weight: ~150kDa (protein weight only)

Amount In comparison to BSA standard, determined by BCA assay. Value rounded to nearest μg:
GCP-IGG-50U   :  50 μg protein
GCP-IGG-100U : 100 μg protein

Glycans :The majority of glycans present on human antibodies are N-link bi-antennary types . These glycans exist in both fucosylated and non-fucosylated forms, with and without bisecting GlcNAcs, and terminate either with 0, 1 or 2 galactoses (the G0, G1 and G2 glycan forms). Sialic acid terminating glycans are also present on native human IgGs.

Form :Dry. Lyophilised powder.

Storage: Keep at -20°C both before and after dissolving. This product is stable for at least 5 years as supplied.

Shipping :The product is shipped at ambient temperature.

Handling :Once dissolved avoid repeated thawing and refreezing, storage over 3 hours at room temperature or above, and exposure to light and long term exposure to acid as these will cause glycan desialylation.

Safety :This product is non-hazardous and has been purified from natural sources certified to be free of all hazardous material including pathogenic biological agents.
