B7-H4, VTCN1, B7S1, B7h.5
Biotinylated Human B7-H4 Protein, Avitag,His Tag (B74-H82E2) is expressed from human 293 cells (HEK293). It contains AA Phe 29 - Ala 258 (Accession # NP_078902).
Predicted N-terminus: Phe 29
This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 28 kDa. The protein migrates as 43-57 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.
B74-H82E2 works best for experiments that test the binding between B7-H4 and candidate antibodies, such as biopanning and other relevant assays.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
