The Recombinant Human KLRB1/CD161 Protein is a biologically active recombinant protein that plays a significant role in various cellular processes and signaling pathways in human biology. This protein is widely employed in immunological research, cell biology studies, protein-protein interaction analyses, and therapeutic development, providing researchers with a reliable tool for investigating KLRB1/CD161 function and its implications in health and disease.
This product (SKU: RPCB0510) is produced using HEK293 cells and features a C-His tag for convenient detection and purification. The protein exhibits a calculated molecular weight of 19.6 kDa with an observed molecular weight of 38-45 kDa under denaturing conditions, achieving ≥ 95 % as determined by SDS-PAGE;≥ 95 % as determined by HPLC., ensuring exceptional quality and consistency for research applications.
High quality, high purity and low endotoxin recombinant Recombinant Human KLRB1/CD161 Protein (RPCB0510), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by SDS-PAGE;≥ 95 % as determined by HPLC.
Formulation:
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
CD161 (NKRP1) is a lectin-like receptor present on NK cells and rare T-cell subsets. We have observed CD161 expression in some cases of T-cell prolymphocytic leukemia (T-PLL) and found it to be useful in follow-up and detection of disease after treatment.
Recombinant Human KLRB1/CD161 Protein was determined by Tris-Bis PAGE under reducing conditions.
The purity of Human CD161 is greater than 95% as determined by SEC-HPLC.
Anti-CD161 Antibody, hFc tag captured on CM5 Chip via Anti-hFc IgG can bind Human CD161, His Tag with an affinity constant of 78.8 nM as determined in SPR assay (Biacore T200).
