Anti-IGF-1 Antibody

Raised in rabbit against human insulin-like growth factor 1 (IGF-1), this polyclonal reagent from Antibodies.com is supplied at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2. The unconjugated antibody is validated for Western blot and immunohistochemistry workflows and recognizes both human and mouse IGF-1, supporting cross-species studies of growth factor signalling, metabolic regulation, and developmental biology research. Each vial delivers 100 µl of antibody, enough for multiple immunoblots or tissue sections depending on dilution. The polyclonal format offers broader epitope coverage than monoclonal alternatives, which can be advantageous when detecting endogenous IGF-1 that may vary between processed and unprocessed forms across tissues. Researchers investigating GH/IGF-1 axis activity, hepatic endocrine signalling, or tumour-associated growth factor expression can apply this reagent to lysates and fixed tissue samples for protein-level readouts. The vial should be kept refrigerated; aliquoting upon first use helps limit repeated freeze-thaw cycles and supports downstream applications where a preservative-free working dilution is needed.
