Rat Thyrotropin subunit beta/TSHB ELISA Kit

This competitive ELISA kit from Assay Genie is designed for the sensitive detection of thyrotropin subunit beta (TSHB) in rat samples. It uses a coated-antigen assay format with colorimetric readout and accepts serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid sample types.

Reported performance includes a sensitivity of 0.094 uIU/mL and a detection range of 0.156–10 uIU/mL. Linearity across serum, EDTA plasma and heparin plasma falls within 80–105% at dilutions of 1:2, 1:4 and 1:8, while average recovery ranges from 92% to 98% across the same sample matrices. Components are kept sealed at 2–8°C and should not be cryopreserved.

TSHB is the beta subunit of thyroid-stimulating hormone and a key regulator of thyroid function, with dysregulation linked to disorders such as hypothyroidism and hyperthyroidism. The kit is positioned as a research tool for investigating TSHB's role in thyroid biology and related metabolic processes.
