Human Surfactant Associated Protein J/SPJ ELISA Kit

A sandwich ELISA, double antibody assay from Assay Genie, this kit is designed for the precise measurement of Surfactant Associated Protein J (SP-J) levels in human biological samples. It is validated for use with serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples, and provides high sensitivity and specificity for research applications involving lung physiology and respiratory health.

The assay delivers a sensitivity of 0.188 ng/mL and a measuring range of 0.313-20 ng/mL, with absorbance read at 450 nm following colorimetric detection using TMB substrate. Storage is at 2-8°C for 12 months. SP-J is a key protein associated with surfactant production in the lungs, and imbalances in its levels have been linked to respiratory disorders such as pulmonary fibrosis and asthma, making the kit a valuable tool for biomarker research and the development of new treatment strategies.
