FITC-Labeled Mouse IgG1 Antibody Isotype Control (DNP-FM1A1) is a chimeric monoclonal antibody recombinantly expressed from human 293 cells (HEK293), which combines the variable region of a mouse monoclonal antibody with human IgG1 constant domain. The mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with DNP.
Specifically reacts with DNP (Dinitrophenyl) and DNP conjugated proteins.
The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular sieve treatment during purification process.
The FITC to protein molar ratio is 1-3.
Flow Cytometry (Used as an Isotype Control for FM3-FY45 and FM3-FY45P1).

2e5 of Anti-CD19 CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of FITC-Labeled Mouse IgG1 Antibody Isotype Control (Cat. No. DNP-FM1A1) and positive control FITC-Labeled Monoclonal Anti-FMC63 scFv Antibody, Mouse IgG1 (Cat. No. FM3-FY45P1) respectively, and FITC signal was used to evaluate the binding activity (QC tested).
5e5 of PBMCs were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of FITC-Labeled Mouse IgG1 Antibody Isotype Control (Cat. No. DNP-FM1A1), and FITC signal was used to evaluate the binding activity (QC tested).
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.
