Clone 53/1 used to detect GDF9 expression by ELISA
Image caption: GDF9 ELISA. A GDF9 ELISA was developed to measure the amount of GDF9 in HEK-293T conditioned medium. Recombinant mouse GDF9 (●) was used as a standard, and the specificity of the assay was assessed using a range of TGF-β family members; wild-type human GDF9 (♦), human GDF9 L40V (◊), human BMP15 (□), human activin A (○), and human TGF-β3 (▾). Dilutions of concentrated media from cells transfected with empty vector, pcDNA3.1 (r), were included as controls. The ELISA has a specificity of less than 0.1%, with a sensitivity of 0.2 ng/mL. Values represent mean ± SEM in duplicate, from a representative experiment. (Simpson, C et al.)
