Quantitative Human POSTN (Glycosylated) Sandwich ELISA Kit (CAT#: GLJF-0325-HX889)

Product Description	The quantitative human POSTN (glycosylated) sandwich ELISA kit is designed to detect human periostin/osteoblast specific factor 2 (POSTN) levels. It is suitable for various biological samples such as tissue homogenates, serum, or plasma. Its sensitivity is 1.624 ng/mL, which can accurately detect low concentrations of POSTN in the sample.

Application	The quantitative human POSTN (glycosylated) sandwich ELISA kit is widely used to assess the expression levels of POSTN, helping to understand its role in cardiovascular.
Precision	Intra-Assay: n=20, CV <8%; Inter-Assay: n=20, CV <10%;
Recovery	Serum sample: n=5, 90-100%; Plasma sample: n=4, 90-100%;
Standard Curve	The standard curve is for reference only, and a new standard curve should be generated for each set of samples tested.
