Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 647 Conjugate) #4414
Specificity / Sensitivity
F(ab')2 fragments are prepared from goat antibodies that have been adsorbed against pooled human serum, mouse serum, plasmacytoma/hybridoma proteins and purified human paraproteins.
Flow cytometric analysis of Jurkat cells, untreated (green) or treated with LY294002 #9901, Wortmannin #9951 and U0126 #9906 (blue), using Phospho-S6 Ribosomal Protein (Ser235/236) (D57.2.2E) XP® Rabbit mAb #4858 detected with Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 647 Conjugate) compared to a nonspecific negative control antibody (red).
Confocal immunofluorescent analysis of mitotic HeLa cells using β-Tubulin (9F3) Rabbit mAb #2128 detected with Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 647 Conjugate) (blue) and Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb (Alexa Fluor® 555 Conjugate) #3475 (red).
High Content Screening
High content analysis of A549 cells exposed to varying concentrations of LY294002 (#9901) for 3 hrs, followed by 100 ng/mL EGF for 20 minutes. With increasing concentrations of LY294002, a significant decrease (~5 fold) in phospho-S6 Ribosomal Protein (Ser235/236) signal as compared to the uninhibited control was observed. When using phospho-S6 as a measurement, the IC50 of this compound was 3.06 μM. Data were generated on the Acumen® HCS platform using Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 647 Conjugate).
Anti-rabbit IgG (H+L) F(ab')2 Fragment was conjugated to Alexa Fluor® 647 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.
This product has been optimized for use as a secondary antibody in immunofluorescent applications.
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.
