Source

Biotinylated Human LILRB5 / CD85c / LIR-8, Fc Tag (CDC-H82F8) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Gly 458 (Accession # O75023-1).

Predicted N-terminus: Gly 24

Molecular Characterization

LILRB5(Gly 24 - Gly 458)O75023-1
Fc(Pro 100 - Lys 330)P01857
Avi

This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).

The protein has a calculated MW of 75.8 kDa. The protein migrates as 90-105 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Biotinylation

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

Biotin:Protein Ratio

The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Contact us for customized product form or formulation.

Reconstitution

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss is observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.

Background

Leukocyte immunoglobulin-like receptor subfamily B member 5 (LILRB5), also known as CD85c and LIR-8, belongs to the leukocyte immunoglobulin-like receptor (LIR) family of transmembrane glycoproteins that negatively regulate immune cell activation. Several other LIR subfamily B receptors are expressed on immune cells where they bind to MHC class I molecules on antigen-presenting cells and inhibit stimulation of an immune response.
