Anti-JAK2 (Ab-570) Antibody

This polyclonal antibody from Antibodies.com targets JAK2 (Janus Kinase 2), a cytoplasmic non-receptor tyrosine kinase that couples type I cytokine receptor activation to downstream STAT transcriptional pathways. Raised in Rabbit and supplied as 100 µl of unconjugated antiserum, the reagent is validated for Western blot and immunofluorescence workflows on Human and Mouse samples. Researchers working on JAK/STAT signaling, erythropoietin or thrombopoietin signal transduction, or myeloproliferative neoplasm biology can use the polyclonal format to detect the ~130 kDa JAK2 protein across multiple epitopes on the same target.

Because the preparation is unconjugated, it integrates cleanly into secondary-detection schemes — HRP- or fluorophore-labeled anti-rabbit reagents — so the same primary serves both chemiluminescent Western blot membranes and fixed-cell imaging. Cross-species reactivity with Human and Mouse supports comparative studies in cultured lines and primary tissue. Standard polyclonal-antibody handling applies: store the vial frozen at -20 °C in small aliquots to limit freeze-thaw cycles and preserve binding activity. Shipped as a single 100 µl vial.
