Anti-JAK1 (D1028) Antibody

Janus kinase 1 (JAK1) is a cytoplasmic non-receptor tyrosine kinase essential for cytokine-driven JAK-STAT signal transduction, and the unconjugated rabbit polyclonal reagent from Antibodies.com provides immunohistochemistry-based detection of this target in human, mouse, and rat tissue sections. Supplied as a 100 µl liquid aliquot at approximately 1 mg/ml in phosphate buffered saline (pH ~7.2) with 0.05% sodium azide added as preservative, the antibody supports research into interferon responses, hematopoietic regulation, and pathway dysregulation in inflammatory disease and tumor biology.

Because the reagent is polyclonal, it recognizes multiple epitopes across the JAK1 protein, which can be useful when probing isoform variants or post-translational modifications. The unconjugated format allows pairing with a researcher's preferred secondary detection chemistry for IHC workflows. Refrigerate upon arrival, protect from light, and prepare working aliquots of the stock to limit freeze-thaw cycles over the shelf life of the product.
