Anti-mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4408


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

Species cross-reactivity is determined by western blot.

Applications Key: F=Flow Cytometry, IF-IC=Immunofluorescence (Immunocytochemistry),

Specificity / Sensitivity

F(ab')2 fragments are prepared from goat antibodies that have been adsorbed against human IgG and human serum.



Anti-Mouse IgG (H+L) F(ab')2 Fragment antibody was conjugated to Alexa Fluor® 488 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-Mouse IgG (H+L) F(ab’)2 Fragment在最佳条件下结合了 Alexa Fluor ® 488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。

Flow cytometric analysis of untreated Jurkat cells using Akt (5G3) Mouse mAb #2966 detected with Anti-Mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) (green) compared to a nonspecific negative control antibody (red).流式细胞术分析Jurkat细胞,所用抗体为Akt (5G3) Mouse mAb #2966,检测抗体为Anti-Mouse IgG (H+L), F(ab’)2Fragment (Alexa Fluor ® 488 Conjugate) (绿色) ,与非特异性阴性对照抗体(红色)作对比。

High Content Screening

High Content Screening

High content analysis of A439 cells exposed to varying concentrations of caffeine for 30 min prior to and 1.5 hr following a 100 mJ UV-treatment. With increasing concentrations of caffeine, a significant decrease (~2.5 fold) in phospho-p53 signal as compared to the UV-treated control was observed. When using phospho-p53 as a measurement, the IC50 of this compound was 2.95 mM. Data was generated on the Acumen® HCS platform using Anti-Mouse IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate).高通量分析A439细胞,该细胞暴露于咖啡因30分钟,然后用100J UV处理1.5个小时。与UV处理的对照组相比较,随着咖啡因浓度的增加, phospho-p53信号显著降低(约2.5倍)。当采用 phospho-p53检测时,IC50为2.95mM。数据时以Acumen ® HCS为平台生成的,所用抗体为Anti-Mouse IgG (H+L), F(ab’)2 Fragment (Alexa Fluor ® 488 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 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.
