Human Chorionic Gonadotropin Alpha Polypeptide (CGa) ELISA Kit

A competitive ELISA platform from Assay Genie, this kit is built around quantitative measurement of the alpha polypeptide subunit shared by human chorionic gonadotropin, luteinizing hormone, follicle-stimulating hormone, and thyroid-stimulating hormone. Because free circulating alpha subunit concentrations can rise during pregnancy-related endocrine studies and in certain trophoblastic tumor investigations, the assay is commonly adopted in placental biology research, glycoprotein hormone biosynthesis studies, and oncology biomarker work.

The format delivers a colorimetric readout on a microplate and accepts a broad matrix of human research samples, including serum specimens, plasma samples, tissue homogenate preparations, cell lysates, and conditioned cell culture medium. Critical reagents are supplied in single-use vials; reconstituted components should be kept refrigerated at 4 °C and protected from repeated freeze-thaw cycles. Intended for in vitro research use only, the package includes pre-coated plate, lyophilized standards, detection antibody, and substrate to support complete standard-curve generation in every run.
