Synonym

CD56, MSK39, NCAM1, N-CAM-1

Source

Human NCAM-1, His Tag (NC1-H5223) is expressed from human 293 cells (HEK293). It contains AA Leu 20 - Gly 718 (Accession # P13591-2).

Predicted N-terminus: Leu 20

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 79.3 kDa. The protein migrates as 100-120 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 0.01 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 500 mM NaCl, pH8.0 with trehalose as protectant.
