Quantitative Human FSTL1 (Glycosylated) Sandwich ELISA Kit (CAT#: GLJF-0525-HX548)

Product Description	The quantitative human FSTL1 (glycosylated) sandwich ELISA kit is designed to detect human follistatin like protein 1 (FSTL1) levels. FSTL1 is a secreted glycoprotein that belongs to the follistatin family, which plays a role in regulating cell growth, differentiation, and tissue development. The kit is suitable for various biological samples such as serum, plasma. Its sensitivity is 0.216 ng/mL, which can accurately detect low concentrations of FSTL1 in the sample.
