Patent ID: 8269063

Claim:
A method for identifying a protein which has an elevated binding activity towards phosphorylated alpha-1,4-glucans, compared to non-phosphorylated alpha-1,4 glucans, comprising a) incubating protein extracts in preparations separate from one another with i. phosphorylated alpha-1,4-glucans and ii. non-phosphorylated alpha-1,4-glucans, b) dissolving proteins specifically bound to the i. phosphorylated alpha-1,4-glucans from step a) i and ii. proteins specifically bound to the non-phosphorylated alpha-1,4-glucans from step a) ii in preparations separate from one another and c) identifying proteins which exhibit an elevated binding activity towards phosphorylated alpha-1,4-glucans used in step b) i, compared to non-phosphorylated alpha-1,4-glucans used in step b) ii.
