Source

Biotinylated Human Frizzled-4 Protein, His,Avitag (FZ4-H82E3) is expressed from human 293 cells (HEK293). It contains AA Phe 37 - Glu 180 (Accession # AAI14528).

Predicted N-terminus: Phe 37

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 20.2 kDa. The protein migrates as 27-33 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
