Biotinylated Human LILRA1 / CD85i / LIR-6 Protein, His,Avitag™

分子别名(Synonym)

LILRA1,LIR6,CD85i,LIR-6

表达区间及表达系统(Source)

Biotinylated Human LILRA1, His,Avitag (LI1-H82E8) is expressed from human 293 cells (HEK293). It contains AA Pro 17 - Asn 461 (Accession # O75019-1).

Predicted N-terminus: Pro 17

蛋白结构(Molecular Characterization)

Online(Pro 17 - Asn 461) O75019-1

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.

The protein has a calculated MW of 52.2 kDa. The protein migrates as 60-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

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

蛋白标记度(Biotin:Protein Ratio)

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

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

重构方法(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.

存储(Storage)

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

Please avoid repeated freeze-thaw cycles.

This product is stable after storage at:

  1. -20°C to -70°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Biotinylated Human LILRA1, His,Avitag (Cat. No. LI1-H82E8) SDS-PAGE gel

Biotinylated Human LILRA1, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human ANGPTL7, His Tag (Cat. No. AN7-H52H5) at 5 μg/mL (100 μL/well) can bind Biotinylated Human LILRA1, His,Avitag (Cat. No. LI1-H82E8) with a linear range of 0.313-2.5 μg/mL (QC tested).

Protocol

背景(Background)

Leukocyte immunoglobulin-like receptors (LILRs) are inhibitory, stimulatory or soluble receptors encoded within the leukocyte receptor complex. Some LILRs are extensively polymorphic, and exhibit evidence for balancing selection and association with disease susceptibility. LILRA1 (LIR-6) can recognize MHC (major histocompatibility complex) class I or class I-like molecules, and high levels of sequence similarity among LILRA1, LILRA2 (ILT1), LILRA3 (ILT6) and LILRB1/B2.
