Protocol to isolate glycoproteins from cultured mammalian cells and tissue samples using wheat germ agglutinin precipitation
Summary: Wheat germ agglutinin (WGA) precipitation enables selective enrichment of glycoproteins such as density-enhanced phosphatase (DEP-1) from protein lysates. Here, we present a protocol to isolate glycoproteins from cultured mammalian cells and tissue samples using WGA agarose beads. We descri...

| Summary: | Summary: Wheat germ agglutinin (WGA) precipitation enables selective enrichment of glycoproteins such as density-enhanced phosphatase (DEP-1) from protein lysates. Here, we present a protocol to isolate glycoproteins from cultured mammalian cells and tissue samples using WGA agarose beads. We describe steps for lysate preparation, bead incubation, and sequential washing to remove unbound proteins, followed by elution and denaturation. We then detail procedures for SDS-PAGE and western blot analysis to assess glycoprotein enrichment and binding specificity.For complete details on the use and execution of this protocol, please refer to Chopra et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics. |
