General Notes
This product (Catalog No. DPABH-01561) is a rabbit-derived polyclonal antibody raised against human OXSR1, targeting the amino acid region 1–288 of the protein. This antibody exhibits cross-reactivity with Human OXSR1 from mouse and rat. It has been affinity purified by Protein A. Oxidative-stress responsive 1(OXSR1) is also named as KIAA1101, OSR1 and belongs to the STE Ser/Thr protein kinase family. It contains an N-terminal Ste20-like ser/thr kinase domain and 2 C-terminal regions, which has a putative caspase-3 cleavage site at the end. OXSR1's interaction with WNK1 is required for NKCC function, and it modulates the G protein sensitivity of PAK by phosphorylation of PAK1.Western blot analysis detected Oxsr1 at an apparent molecular mass of 58 kD in all mouse tissues examined except thymus. Cell fractionation and immunofluorescence analysis of HeLa cells showed that OXSR1 was distributed throughout the cell and OXSR1 could phosphorylate a test substrate and itself(PMID:14707132).
DPABH-01561 is suitable for use in Western blot (WB) (1:500–1:2,000), IP (0.5-4.0 μg for 1.0-3.0 mg of total protein lysate), IHC (1:50–1:500), IF/ICC (1:50–1:500) applications.
DPABH-01561 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
