Biotinylated Human Kallikrein 3 Protein, His,Avitag (KA3-H82E4) is expressed from human 293 cells (HEK293). It contains AA Ala 18 - Pro 261 (Accession # P07288-1).
Predicted N-terminus: Ala 18
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 30.5 kDa. The protein migrates as 33-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Passed as determined by the SABA assay / HABA assay / binding ELISA.
Less than 1.0 EU per μg by the LAL method / rFC method.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.
