Secondary Antibodies
Anti-mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 555 Conjugate) #4409
Specificity / Sensitivity
F(ab')2 fragments are prepared from goat antibodies that have been adsorbed against human IgG and human serum.
IF-IC
Confocal immunofluorescent analysis of HeLa cells using S6 Ribosomal Protein (54D2) Mouse mAb #2317 detected with Anti-Mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 555 Conjugate) (red, left) compared to an isotype control (right). Actin filaments have been labeled with fluorescein phalloidin. Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
High Content Screening
High content analysis of C2C12 cells exposed to varying concentrations of LY294002 #9901 for 2 hours. With increasing concentrations of LY294002, a significant decrease (~20 fold) in phospho-S6 Ribosomal protein (Ser235/236) signal as compared to the untreated control was observed. When using phospho-S6 Ribosomal protein as a measurement, the IC50 of this compound was 2.3 μM. Data was generated on the Acumen® HCS platform using Anti-Mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 555 Conjugate).
Description
Anti-Mouse IgG (H+L) F(ab')2 Fragment was conjugated to Alexa Fluor® 555 fluorescent dye under optimal conditions and formulated at 2 mg/ml. This F(ab')2 fragment results in less non-specific binding to cells through Fc receptors.
Directions for Use
The optimal dilution of the anti-species antibody should be determined for each application. However, a final dilution of 1:1000 should yield acceptable results for most immunofluorescent applications.
Applications
This product has been optimized for use as a secondary antibody in immunofluorescent applications.
Background
Fluorescent anti-species IgG conjugates are ideal for flow cytometry and immunofluorescence. Cell Signaling Technology’s strict quality control procedures assure that each conjugate provides optimal specificity and fluorescence.
