ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 1E16 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects MHC class II antigen DPB1 (HLA-DPB1). It targets an epitope within 18 amino acids from the extracellular domain.

Immunogen

KLH-conjugated linear peptide corresponding to 18 amino acids from the extracellular domain of human MHC class II antigen DPB1 (HLA-DPB1).

Application

Quality Control Testing

Evaluated by Western Blotting in Human tonsil tissue lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected HLA-DPB1 in Human tonsil tissue lysate.

Tested Applications

Flow Cytometry Analysis: 1 µg from a representative lot detected HLA-DPB1 in one million Human peripheral blood mononuclear cells (PBMC).

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected HLA-DPB1 in HEK 293 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected HLA-DPB1 in human tonsil tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound HLA-DPB1 peptide with a KD of 1.0 x 10-7 in an affinity binding assay.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

HLA class II histocompatibility antigen, DP beta 1 chain (UniProt: P04440; also known as HLA class II histocompatibility antigen, DP(W4) beta chain, MHC class II antigen DPB1) is encoded by the HLA-DPB1 (also known as HLA-DP1B) gene (Gene ID: 3115) in human. HLA-DPB1 is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-29), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 30-225), a transmembrane domain (aa 226-246), and a cytoplasmic domain (aa 227-258). It plays a central role in the immune system by presenting peptides derived from extracellular proteins. It is a MHC class II molecule that forms a heterodimer of α and β subunits. Its expression is observed in antigen presenting cells. It is reported to bind peptides derived from antigens that ACCESS^™ the endocytic route of antigen presenting cells (APC) and present them on the cell surface for recognition by the CD4 T-cells. Its peptide binding cleft accommodates peptides of 10-30 residues. Endocytosed exogenous antigens are readily available for presentation and compete with endogenous proteins on their way to degradation in lysosomes. Genetic variants in HLA-DPB1 are associated with increased risk of severe aplastic anemia. A mutation in HLA-DPB1 gene (HLA-DPB1Glu69) is observed in chronic beryllium disease. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
