Our Anti-ATRIP (Ser239) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse ATRIP (Ser239) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of mouse testicular lysate showing specific immunolabeling of the ~86 kDa ATRIP protein phosphorylated at Ser239 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (λ-Ptase, 800 units/1mg protein for 30 minutes).
Anti-ATRIP (Ser239) Antibody
ATRIP, ATR interacting protein, binds to ATR to regulate ATR expression, and is an essential component of the DNA damage checkpoint pathway (Cortez et al, 2001). ATR is recruited to DNA lesions in part through its association with ATRIP, which in turn interacts with the single-stranded DNA binding protein RPA (Ball et al, 2007). DNA replication forks may stall as a result of DNA damage causing phosphorylation of several proteins, including BRCA1 when colocalizing with ATR/ATRIP complex and RPA (Venere et al, 2007). The DNA replication fork stall coincides with BRCA1 directly phosphorylating ATRIP at Ser-239 (Venere et al, 2007).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser239 of human ATRIP, conjugated to keyhole limpet hemocyanin (KLH).
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Prepared from rabbit serum by affinity purification via sequential chromatography on phospho and non-phosphopeptide affinity columns.
10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
Specific for endogenous levels of the ~86 kDa ATRIP protein phosphorylated at Ser239. The antibody also recognizes a band at ~32 kDa.
Western blots performed on each lot.
