Anti-OXSR1 (OSR1) Antibody

Rabbit-derived polyclonal antibody targeting human OXSR1 (Oxidative Stress Responsive Kinase 1), a STE20-family serine/threonine kinase that regulates ion transporter activity through phosphorylation of NKCC1, NCC, and SPAK/OSR1 signaling complexes.

Provided by Antibodies.com as a 100 µl unconjugated reagent for Western blot and immunofluorescence applications, the antibody recognizes endogenous OSR1 in human cells and tissues. Researchers investigating renal salt handling, hypertension mechanisms, and cellular osmotic stress responses use this reagent to map kinase expression and activation status.

Polyclonal reactivity increases the likelihood of binding across multiple OSR1 epitopes, improving tolerance for minor protein variations between samples. The unconjugated format allows flexible pairing with secondary antibodies conjugated to HRP, fluorophores, or biotin depending on the assay design.

Store refrigerated and protect from light; avoid repeated freeze-thaw cycles by aliquoting on first use.
