Description

Mouse Monoclonal Secondary Antibody

Description: The monoclonal antibody r2a-21B2 recognizes Rat IgG2a antibodies and can be used as a second step reagent in flow cytometry and microscopy. The monoclonal does not recognize other rat isotypes nor does it crossreact to mouse IgG2a or any mouse isotype antibodies. Applications Reported: This r2a-21B2 antibody has been reported for use in flow cytometric analysis, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, and immunocytochemistry. Applications Tested: This r2a-21B2 antibody has been tested by flow cytometric analysis and immunohistochemstry using rat IgG2a primary antibody. This can be used at less than or equal to 0.5 μg per test for flow cytometry or 10 μg/mL for IHC. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser. Filtration: 0.2 μm post-manufacturing filtered.

Anti-Rat secondary antibodies are affinity-purified antibodies with well-characterized specificity for rat immunoglobulins and are useful in the detection, sorting or purification of its specified target. Secondary antibodies offer increased versatility enabling users to use many detection systems (e.g. HRP, AP, fluorescence). They can also provide greater sensitivity through signal amplification as multiple secondary antibodies can bind to a single primary antibody. Most commonly, secondary antibodies are generated by immunizing the host animal with a pooled population of immunoglobulins from the target species and can be further purified and modified (i.e. immunoaffinity chromatography, antibody fragmentation, label conjugation, etc.) to generate highly specific reagents.
