Recombinant Human MUSK Protein, Fc tagged, Biotin Labeled

• Cat.No.: MUSK-43H
• Product Overview: Recombinant Human MUSK Protein (Leu24-Thr495) with Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Chinese Hamster Ovary cell line.

Specification

• Description: This gene encodes a muscle-specific tyrosine kinase receptor. The encoded protein may play a role in clustering of the acetylcholine receptor in the postsynaptic neuromuscular junction. Mutations in this gene have been associated with congenital myasthenic syndrome. Alternatively spliced transcript variants have been described.
• Source: CHO
• Species: Human
• Tag: C-Fc
• Protein length: 24-495aa
• Conjugation/Label: Biotin
• Form: Disulfide-linked homodimer, Biotinylated via Avi-tag
• Bio-activity: Measured by its binding ability in a functional ELISA. When Biotinylated Recombinant Human MuSK Fc Chimera Avi-tag is immobilized onto a Streptavidin coated plate at 2 μg/mL (100 μL/well), in the presence of Recombinant Human Agrin, it binds to Recombinant Human LRP-4 with an ED50 of 0.600-4.80 ng/mL.
