Source

Human LILRB3, Fc Tag (CDA-H5250) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Glu 443 (Accession # AAB68668(P288R)).

Predicted N-terminus: Gly 24

Molecular Characterization

LILRB3(Gly 24 - Glu 443)AAB68668(P288R)
Fc(Pro 100 - Lys 330)P01857

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 72.8 kDa. As a result of glycosylation, the protein migrates as 90-115 kDa under reducing (R) condition, and 150 kDa under non-reducing (NR) condition (SDS-PAGE).

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.

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.
 

SDS-PAGE

Human LILRB3, Fc Tag (Cat. No. CDA-H5250) SDS-PAGE gel

Human LILRB3, Fc Tag on SDS-PAGE under reducing (R) and no-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

 

Background

Leukocyte immunoglobulin-like receptor subfamily B member 3 is also known as LILRB3,ILT-5 or CD85a. LILRB3 plays an role as receptor for class I MHC antigens, which activated upon coligation of LILRB3 and immune receptors, such as FCGR2B and the B-cell receptor. LILRB3 and LILRA6 represent a pair of inhibitory/activating receptors with identical extracellular domains and unknown ligands. LILRB3 can mediate inhibitory signaling via immunoreceptor tyrosine-based inhibition motifs in its cytoplasmic tail whereas LILRA6 can signal through association with an activating adaptor molecule, FcRγ.
