Simple Western™ 1:10 - 1:50
Immunoprecipitation 1:50

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity/Sensitivity

Phospho-Rad50 (Ser635) Antibody recognizes endogenous levels of Rad50 protein only when phosphorylated at Ser635.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser635 of human Rad50 protein. Antibodies are purified by peptide affinity chromatography.

Background

The DNA repair protein Rad50 is a member of the structural maintenance of chromosomes (SMC) family and plays an important role in cell cycle checkpoint signaling and double-strand break repair in response to DNA damage (1-4). Rad50 forms a complex with Mre11 and NBS1 that becomes activated in response to DNA damage (3). In normal human cells, the MRN complex acts to tether linear DNA molecules, providing a flexible link between DNA ends (1). Genomic instability and cancer have been shown to develop in cells with genetic mutations affecting the proteins in the MRN complex (2). ATM-dependent phosphorylation of Rad50 at Ser635 in response to DNA damage is important in regulating downstream signaling, DNA repair, and checkpoint control (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western blot analysis of extracts from 293 and C6 cells, untreated (-) or treated with UV (100 mJ, 4 hr and 2 hr respectively; +), using Phospho-Rad50 (Ser635) Antibody (upper), Rad50 Antibody #3427 (middle), or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Phosphorylation of Rad50 protein at Ser635 is induced by UV treatment as expected.

Western blot analysis of extracts from MCF7 and 293T cells, untreated (-) or treated with Neocarzinostatin (0.5 μg/mL, 1 hr; +), using Phospho-Rad50 (Ser635) Antibody (upper), Rad50 Antibody #3427 (middle), or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Phosphorylation of Rad50 protein at Ser635 is induced by neocarzinostatin treatment as expected.

Simple WesternTM analysis of lysates (0.1 mg/mL) from 293 + Hydroxyurea cells using Phospho-Rad50 (Ser635) Antibody #74778. The virtual lane view (left) shows the target band (as indicated) at 1:10 and 1:50 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:10 (blue line) and 1:50 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the JessTM Simple Western instrument from ProteinSimple, a BioTechne brand, using the 12-230 kDa separation module.
