The fetuin glycoprotein standard was developed for use during glycan release and labeling(particularly for DMB sialic acid analysis). Fetuin exists in a variety of glycoforms containing bi-, tri-, and tetra-antennary oligosaccharides with variable sialylation, as well as O-linked glycans.

Source :Fetal calf serum

Form :Dry. Lyophilised powder.

Molecular Weight: 36 kDa (protein weight only)

Analysis
Fetuin glycans were released from the Fetuin Glycoprotein Standard (Cat# GCP-FET-05) using PNGase-F.

Following release the glycans were labeled using 2-Aminobenzamide (2-AB) using the LudgerTag 2-AB Glycan Labeling Kit (Cat# LT-KAB-A2).

Storage: Refrigerate (-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, 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.
