Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 555 Conjugate) #4413


Applications Species-Reactivity Sensitivity MW (kDa) Isotype
HCA Goat

Species cross-reactivity is determined by western blot.

Applications Key: HCA=High Content Analysis, IF-IC=Immunofluorescence (Immunocytochemistry),

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.



Anti-Rabbit 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.

Anti- Rabbit IgG (H+L) F(ab’)2 Fragment在最佳条件下结合了 Alexa Fluor ® 555荧光染料,浓度为2mg/ml. F(ab’)2片段可以减少通过Fc受体的非特异性结合。

High Content Screening

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® 555 Conjugate).图 高通量分析A549细胞,该细胞暴露于不同浓度的LY294002 #9901 3个小时。然后用100ng/mlde EGF 处理20分钟。与未抑制组相比较,随着LY294002 #9901浓度的增加phospho-S6 Ribosomal Protein (Ser235/236)信号显著降低(约5倍)。当phospho-S6 Ribosomal Protein 检测时,IC50为3.06mM。数据时以Acumen ® HCS为平台生成的,所用抗体为Anti-Rabbit IgG (H+L), F(ab’)2 Fragment (Alexa Fluor ® 555 Conjugate)。


This product has been optimized for use as a secondary antibody in immunofluorescent applications.


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 immunofluorescentapplications.



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.
