Q:

Per customer request, can you please provide the following information about this kit:
a. Capture antibody or capture antigen – immunogen type, sequence (including species source and accession no. if available), expression host, clonality and host species.
b. Detection antibody (if applicable) - immunogen type, sequence (including species source and accession no. if available), expression host, clonality and host species.
c. Standard – if recombinant protein, please specify sequence (including species source and accession no. if available) and expression host.
d. Please provide your reference data for human plasma samples.
e. Did you study the cross-reactivity or interference between Growth Differentiation Factor 11 (GDF11) and analogues? If yes, please provide the corresponding data.

A:
Thanks for your inquiry!
CSB-EL009344HU
Capture antibody is mouse monoclonal antibody and immunogen is CHO cell-derived recombinant protein，full length.
Detection antibody is goat polyclonal antibody and immunogen is CHO cell-derived recombinant protein, fragment. Standard is CHO cell-derived recombinant protein.
We tested undiluted normal serum and plasma samples before and the test value is ND--40pg/ml.
There is no cross-reactivity with human GDF15, human GDF5 and human GDF9.

靶點詳情

  • 功能：
    Secreted signal that acts globally to regulate anterior/posterior axial patterning during development. May play critical roles in patterning both mesodermal and neural tissues. It is required for proper vertebral patterning and orofacial development. 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.
