The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Biological activityThe biological activity of ab116171 is determined by its ability to inhibit Wnt3a induced alkaline phosphatase production in MC3T3-E1 cells. The expected ED50 for this effect is 40-60 ng/ml.
Endotoxin level< 0.100 Eu/µg
% SDS-PAGE. The purity of ab116171 is greater than 80% by SDS-PAGE gel and HPLC analyses.

Protein Wnt-7a precursor
Proto oncogene Wnt7a protein
proto-oncogene wnt7a protein
wingless-type MMTV integration site family, member 7A
FunctionLigand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. Signaling by Wnt-7a allows sexually dimorphic development of the mullerian ducts.
Tissue specificityExpression is restricted to placenta, kidney, testis, uterus, fetal lung, and fetal and adult brain.
Involvement in diseaseDefects in WNT7A are the cause of limb/pelvis-hypoplasia/aplasia syndrome (LPHAS) [MIM:276820]; also known as absence of ulna and fibula with severe limb deficiency. LPHAS is a limb-malformation disorder characterized by various degrees of limb aplasia/hypoplasia and joint dysplasia. Defects in WNT7A are a cause of Fuhrmann syndrome (FUHRS) [MIM:228930]; also known as fibular aplasia or hypoplasia femoral bowing and poly- syn- and oligodactyly. Fuhrmann syndrome is a distinct limb-malformation disorder characterized also by various degrees of limb aplasia/hypoplasia and joint dysplasia.
Sequence similaritiesBelongs to the Wnt family.
