Product Overview
HM74 (T327) polyclonal antibody detects endogenous levels of HM74B protein. This antibody also recognizes HM74A protein.
HM74, also known as PUMAG or Puma-g, is a member of the G protein coupled receptor (GPCR) superfamily. In humans, HM74 is encoded by two different genes (GPR109A and GPR109B) that produce proteins, namely HM74A and HM74 (or HM74B), which are 96% homologous. In mice and rats, only one gene encodes the HM74 protein (Gpr109a). HM74 is a G(i) protein-coupled receptor that mediates the metabolic effects of nicotinic acid. Localizing to the cell membrane, HM74 is highly expressed in adipocytes, immune cells and spleen.

This antibody has been validated for WB, IHC, IF. Always refer to the product datasheet for recommended dilution ranges and appropriate positive control samples for each application type.
Validated reactivity has been confirmed for Human, Mouse, Rat. Cross-reactivity with additional species may exist based on sequence homology but has not been confirmed by the manufacturer. For unlisted species, we recommend running a preliminary validation experiment.
This antibody was raised in Rabbit. For indirect detection (WB, IHC, IF), select an anti-Rabbit secondary antibody that matches the isotype. For direct detection, check the variant selector for conjugated formats. Confirm secondary antibody compatibility before ordering.

Please refer to the storage conditions on the product label and datasheet. As a general best practice: upon receipt, aliquot into single-use volumes to minimize freeze-thaw cycling, which can progressively reduce antibody performance and lead to aggregation.
Validated reactivity covers Human, Mouse, Rat samples. Performance can vary across different cell lines and tissue types depending on target antigen expression levels and epitope accessibility. We recommend verifying target expression in your specific model system using a known positive control before proceeding to experimental samples.
