Product Details

Description

The product CSB-EL009344HU is a colorimetric ELISA kit for quantitative determination of Growth/differentiation factor 11 (GDF11) in human serum, plasma, or tissue homogenates. GDF11, also called bone morphogenetic protein (BMP11), is a secreted glycoprotein belonging to the TGF-β family of cytokines. GDF11 is broadly expressed in diverse tissues. It plays an important role in anterior/posterior axial patterning during embryogenesis. GDF11 acting as a negative regulator of neurogenesis in the olfactory epithelium and the developing spinal cord. Besides, the involvement of GDF11 in erythropoiesis, aging, cardiovascular disease, diabetes mellitus, cancer, and other diseases has been reported.

This kit has a broad detection range (28 pg/mL-1800 pg/mL), pg-level sensitivity, excellent specificity, good linearity, precision less than 10%, high recovery, and lot-to-lot consistency. It employs the sandwich ELISA technique and enzyme-substrate chromogenic reaction to measure the GDF11 content in the sample. The solution color develops in proportion to the amount of GDF11 in the sample, and the color intensity can be measured by a microplate reader at 450 nm.

Target Background

Function
(From Uniprot)
Secreted signal that acts globally to specify positional identity along the anterior/posterior axis during development. May play critical roles in patterning both mesodermal and neural tissues and in establishing the skeletal pattern (By similarity). Signals through activin receptors type-2, ACVR2A and ACVR2B, and activin receptors type-1, ACVR1B, ACVR1C and TGFBR1 leading to the phosphorylation of SMAD2 and SMAD3
