Sandwich ELISA - Human HLA-DR ELISA Kit (AB223593)

Interpolated concentrations of native HLA-DR in human cell and tissue extract samples.

The concentrations of HLA-DR were measured in duplicates, interpolated from the HLA-DR standard curves corrected for sample dilution and extract load. Undiluted samples are as follows : Daudi cell extract 32.3 μg/mL, Raji cell extract 490 μg/mL, and human skin extract 500 μg/mL. The interpolated dilution factor and corrected values are plotted (mean +/- SD, n=2). The mean HLA-DR concentration was determined to be 52.0 pg/μg in Daudi Extract, 1.93 pg/μg in Raji Extract and 0.85 pg/μg in human skin homogenate extract.

제품 세부 정보

Human HLA-DR ELISA Kit ab223593 is a rapid single-wash 90-min Sandwich ELISA to measure Human HLA-DR in cell culture extracts, tissue homogenate. This SimpleStep sensitivity is 5 pg/mL.

How the assay works

Human HLA-DR SimpleStep ELISA^{^®}employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA^{^®} plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA^{^®} protocol summary in the image section for further details.

Assay Specificity

Our SimpleStep ELISA^® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Human HLA-DR ELISA Kit ab223593 protocol summary

1. Mix: add samples/standards to the wells together with the capture and detector antibody cocktail. Incubate 1 hr at room temperature
2. Wash
3. Add TMB development solution - incubate for 10 min
4. Add Stop solution
5. Read the results on a plate reader at 450 nm

Design your own immunoassay

We offer the antibody pair used in this kit in a BSA and Azide-free format, ready for conjugation:

- Anti-HLA-DR antibody [EPR20209-156] - BSA and Azide free (Capture) ab242928
- Anti-HLA-DR antibody [EPR20209-171] - BSA and Azide free (Detector) ab242928

HLA class II histocompatibility antigen, DR alpha chain (HLA-DR) is the alpha chain of a cell surface receptor heterodimer that binds peptides for presentation to CD4 T cells. The alpha chain is fairly constant between individuals and pairs with varying alleles of the beta chain. HLA-DR has been implicated in multiple auto-immune conditions, as well as graft vs host disease.

타겟 정보

An alpha chain of antigen-presenting major histocompatibility complex class II (MHCII) molecule. In complex with the beta chain HLA-DRB, displays antigenic peptides on professional antigen presenting cells (APCs) for recognition by alpha-beta T cell receptor (TCR) on HLA-DR-restricted CD4-positive T cells. This guides antigen-specific T-helper effector functions, both antibody-mediated immune response and macrophage activation, to ultimately eliminate the infectious agents and transformed cells (PubMed : 15265931, PubMed : 15322540, PubMed : 17334368, PubMed : 22327072, PubMed : 24190431, PubMed : 27591323, PubMed : 29884618, PubMed : 31495665, PubMed : 8145819, PubMed : 9075930). Typically presents extracellular peptide antigens of 10 to 30 amino acids that arise from proteolysis of endocytosed antigens in lysosomes (PubMed : 8145819). In the tumor microenvironment, presents antigenic peptides that are primarily generated in tumor-resident APCs likely via phagocytosis of apoptotic tumor cells or macropinocytosis of secreted tumor proteins (PubMed : 31495665). Presents peptides derived from intracellular proteins that are trapped in autolysosomes after macroautophagy, a mechanism especially relevant for T cell selection in the thymus and central immune tolerance (PubMed : 17182262, PubMed : 23783831). The selection of the immunodominant epitopes follows two processing modes : 'bind first, cut/trim later' for pathogen-derived antigenic peptides and 'cut first, bind later' for autoantigens/self-peptides (PubMed : 25413013). The anchor residue at position 1 of the peptide N-terminus, usually a large hydrophobic residue, is essential for high affinity interaction with MHCII molecules (PubMed : 8145819).
