Using CometChip to Characterize Extracellular Regulators of DNA Repair: Does CD73 Levels in Cancer Cells Affect DNA Repair by Regulating Levels of Intracellular NAD+?

Top 4 Reasons: Why Use CRISPR-Cas9 Antibodies and How?

1. Verification of the success of transfection

Why- If the CRISPR-Cas9 transfection is not successful, it would not be relevant to relate the observations from transfected cells to the expected outcome of gene editing experiment.

RAD51: The cell's 'Mr. Fix-it'

RAD51 is a recombinase protein encoded by RAD51 gene in humans. Human RAD51 family members are highly similar to bacterial RecA and yeast Rad51, both biochemically and structurally. It is a 339-amino acid protein that plays an important role in homologous recombination (HR) of DNA during double-strand break (DSB) repair.

Using BrDU to Study Cell Proliferation

The thymidine analogue bromodeoxyuridine (BrdU) has a long, colorful history of heavy use in molecular and cytokinetic studies (1, 2). BrDU is incorporated into newly synthesized DNA only in S-phase cells, and then immunocytochemically detected with BrDU antibodies. This method allows for extremely accurate and comprehensive comparative studies of a variety of cells ranging from normal to neoplastic.
