抗体来源（Source）
Mouse IgG2a Antibody Isotype Control is a monoclonal antibody recombinantly expressed from human 293 cells (HEK293), which provides higher batch consistency and long term security of supply.
应用（Application）
Flow Cytometry.
种属（Species）
Mouse
亚型（Isotype）
Mouse IgG2a/kappa
特异性（Specificity）
Specifically reacts with DNP (Dinitrophenyl) and DNP conjugated proteins, which is normally not present in Humans or animals. Therefore, DNP-PM487 does not react with any antigen of Human or animal cells.

活性（Bioactivity）-FACS
Flow cytometric analysis of Anti-CD19 CAR-293 cells staining with PE-Labeled Mouse IgG2a Antibody Isotype Control (Cat. No. DNP-PM487) at 1:50 dilution (2 μL of the antibody stock solution corresponds to labeling of 1e6 cells in a final volume of 100 µL), compared with positive control antibody. PE signal was used to evaluate the binding activity (QC tested).
Protocol
背景（Background）
A hapten is a small molecule that can elicit an immune response only when conjugated with a large carrier such as a protein. Typical haptens include drugs, urushiol, quinone, steroids, etc. Peptides and non-protein antigens usually need conjugating to a carrier protein (such as BSA (bovine serum albumin) or KLH (keyhole limpet hemocyanin) to become good immunogens). Additionally, haptens should be administered with an adjuvant to ensure a high quality immune response. It is important that the hapten design (preserving greatly the chemical structure and spatial conformation of target compound), selection of the appropriate carrier protein and the conjugation method are key conditions for the desired specificity anti-hapten antibodies. We design anti-hapten antibodies based on the HaptenDB information.
