Human USF1 ELISA Kit (HUFI05765)

The Upstream Stimulatory Factor 1 (USF1) protein is a member of the basic-helix-loop-helix-leucine zipper family of transcription factors that binds E-box motifs to drive expression of genes involved in glucose and lipid homeostasis. This quantitative immunoassay reagent set from Assay Genie is configured for measuring human USF1, supplied as a 96 Assays pack supporting high-throughput laboratory studies. Researchers studying metabolic syndrome, familial combined hyperlipidemia, atherosclerosis susceptibility, hepatic gluconeogenesis, or circadian transcriptional control have used USF1 quantification in human serum or plasma samples to correlate circulating protein levels with dietary intervention, candidate gene association studies, and endocrine signaling experiments. Each kit includes a pre-coated microplate, detection antibody concentrate, calibrator, and substrate reagents formatted for standard absorbance-based readouts on a compatible plate reader. Reagent components should be stored refrigerated between uses to maintain binding activity through the stated shelf life, and individual vials are intended for research use only across multiple plates when scaled from the 96 Assays configuration. Citation support, lot-specific validation data, and experimental protocol recommendations accompany the kit to facilitate reproducibility in academic and translational research environments.
