Invitrogen™ 53BP1 Recombinant Rabbit Monoclonal Antibody (7H14L12), Alexa Fluor™ Plus 555

Description

Alexa Fluor™ Plus recombinant antibodies are conjugated using new, proprietary dye chemistry so you can generate stunning data. Alexa Fluor™ Plus antibodies represent an advancement in fluorescent conjugate technology. Alexa Fluor™ Plus antibodies provide brighter signal compared to leading Alexa Fluor™ antibodies, providing you with better signal-to-noise for your critical experiments. These antibodies show better specificity and lot-to-lot consistency as these are recombinant antibodies, generated by cloning specific genes for the desired antibodies into an expression vector and expressed in vitro. Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining. Applications Tested: This 53BP1 antibody has been tested by immunocytochemistry and flow cytometric analysis of HeLa cells. This may be used for immunocytochemistry at 5 μg/mL and for flow cytometry at less than or equal to 0.25 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation:...

53BP1 (P53-binding protein 1) plays a critical role in tumor suppression and is a putative substrate of ATM kinase. Upon DNA damage, 53BP1 is phosphorylated and localizes to the presumptive sites of damage, specifically, double-strand breaks. 53BP1 may have a role in checkpoint signaling during mitosis, enhances TP53-mediated transcriptional activation, and participates in DNA repair by maintaining genomic stability.
