Human LILRB1 HEK293 Overexpression Lysate


Human LILRB1 HEK293 Overexpression Lysate: 产品信息

This Human LILRB1 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of LILRB1 protein (Cat: 16014-H08H) from the overexpression lysate was verified.
HEK293 Cells
A DNA sequence encoding the human LILRB1 (ADJ55949.1) (Met1-His458) was expressed with a C-terminal polyhistidine tag.
The recombinant human LILRB1 comprises 446 amino acids and has a predicted molecular mass of 48.6 kDa. The apparent molecular mass of the protein is approximately 61-68 kDa in SDS-PAGE under reducing conditions due to glycosylation.

Human LILRB1 HEK293 Overexpression Lysate: 使用指南

Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
1.  Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2.  Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

LILRB1 背景信息

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.
