Immunofluorescence analysis of F(ab')2-Goat anti-Mouse IgG (H+L) Cross-Adsorbed Secondary Antibody, RPE (A10543) was performed using MCF-7 cells stained with Cytokeratin 19 Mouse Monoclonal Antibody (MA512613). The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, blocked with 1% BSA for 1 hour and labeled with mouse primary antibody (1:250 dilutions) for 3 hours at room temperature. F(ab')2-Goat anti-Mouse IgG (H+L) Cross-Adsorbed Secondary Antibody, PE conjugate was used at concentration of 4.0 µg/ml in phosphate buffered saline containing 0.2 % BSA for 45 minutes at room temperature, for detection of cytokeratin 19 in the membrane (Panel a: green). Nuclei (Panel b: blue) were stained with DAPI in SlowFade® Gold Antifade Mountant (S36938). F-actin was stained with Alexa Fluor® 488 Phalloidin (A12379, 1:300) (Panel c: green). Panel d represents the composite image. No nonspecific staining was observed with the secondary antibody alone (panel f), or with an isotype control (panel e). The images were captured at 60X magnification.

Anti-Mouse secondary antibodies are affinity-purified antibodies with well-characterized specificity for mouse 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.
