LILRB1 Protein, Human, Recombinant (ECD, hFc Tag)

LILRB1 (Leukocyte Immunoglobulin Like Receptor B1) is a Protein Coding gene. The encoded protein belongs to the subfamily B class of LIR receptors which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and two to four cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs) . LILRB1 is encoded within the leukocyte receptor complex on 19q13.4, previously implicated to be a susceptibility region to systemic lupus erythematosus (SLE) . LILRB1 binds to a wide range of Major Histocompatibility Complex Class I molecules (MHCIs) and transduces negative signals that can, for example, prevent the killing of MHCI-expressing cells. LILRB1 transcription is correlated with surface protein expression on NK cells. Diseases associated with LILRB1 include Alzheimer's Disease 12 and Severe Pre-Eclampsia.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant human LILRB1 consists of 673 amino acids and predicts a molecular mass of 73.9 kDa. As a result of glycosylation, it migrates as an approximately 107.6 kDa band in SDS-PAGE under reducing conditions.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
