Human HOPX (Homeodomain-only protein) ELISA Kit (HUFI03909)

The Human HOPX ELISA Kit from Assay Genie provides a quantitative tool to investigate homeodomain-only protein, a 73-amino acid transcriptional co-repressor implicated in cardiac progenitor cell differentiation, lung alveolar type II cell maturation, and tumor suppression. HOPX lacks the conventional DNA-binding homeodomain of typical homeobox proteins and instead modulates serum response factor (SRF) activity and downstream gene programs. Altered HOPX expression has been documented in non-small cell lung carcinoma, colorectal adenocarcinoma, and breast carcinoma specimens, making it a candidate biomarker in oncology research. The microplate format includes all reagents required for the ELISA workflow, with each well receiving 100 µL of sample per the standard protocol. Store the sealed components at 4 degrees C, protect from light, and aliquot input samples to limit repeated freeze-thaw cycles that compromise native protein. This research use only in vitro kit complements studies in developmental biology, pulmonary epithelial differentiation, and cancer biomarker discovery.
