Human/Mouse Wnt-3a Antibody Summary

Species Reactivity
Human, Mouse
Detects human and mouse Wnt-3a in direct ELISAs.
Monoclonal Rat IgG1 Clone # 930769
Protein A or G purified from hybridoma culture supernatant
Chinese hamster ovary cell line CHO-derived recombinant mouse Wnt-3a
Accession # P27467
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Measured by its ability to neutralize Wnt-3a induced Topflash reporter activity in the HEK293T human embryonic kidney cell line. The Neutralization Dose (ND50) is typically 0.15-0.9 μg/mL in the presence of 0.5 μg/mL Recombinant Mouse Wnt-3a.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Topflash Reporter Activity Induced by Wnt-3a and Neutralization by Human/Mouse Wnt-3a Antibody. Recombinant Mouse Wnt-3a (Catalog # 1324-WN) induces Topflash reporter activity in the HEK293T human embryonic kidney cell line in a dose-dependent manner (orange line), as measured by the Topflash Reporter Assay. Under these conditions, Topflash reporter activity elicited by Recombinant Mouse Wnt-3a (0.5 µg/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Human/Mouse Wnt-3a Monoclonal Antibody (Catalog # MAB9025). The ND50 is typically 0.15-0.9 µg/mL.

Background: Wnt-3a

Wnt-3a is one of about 19 vertebrate members of the Wingless-type MMTV integration site (Wnt) family of highly conserved cysteine-rich secreted glycoproteins important for normal developmental processes (1‑3). Wnts bind to receptors of the Frizzled family in conjunction with a coreceptor of the low-density lipoprotein receptor-related protein family (LRP-5 or -6), or the Ryk atypical receptor tyrosine kinase (1, 4). Mouse Wnt-3a is a 44 kDa secreted hydrophobic glycoprotein containing a conserved pattern of 24 cysteine residues (5). Like other Wnts, Wnt-3a is modified by palmitate addition (at Cys 77) following glycosylation, which increases its hydrophobicity, secretion and activity (6, 7). A second site at Ser 209 is modified by palmitoleic acid and also contributes to activity and secretion (8). Mouse Wnt-3a shares 96% amino acid (aa) identity with human Wnt-3a, and 97% with bovine and canine Wnt-3a. The rat Wnt-3a precursor as it is apparently translated shares 100% aa identity with mouse Wnt-3a aa 63-352 (9). Wnt-3a also shares 87% aa identity with Wnt-3. During development, Wnt-3a is morphogen that is thought to coordinate somitogenesis and mesoderm boundary determination, and is expressed at the same locations and times as Wnt-2b and Wnt-5a (10). When Wnt-3a is deleted, mice fail to develop a hippocampus, and show defects in anterior-posterior patterning, somite development and tailbud formation (10-13). Recombinant Wnt-3a promotes proliferation of committed stem cell lineages in vitro, and may help maintain the cells in an undifferentiated state (6, 14) For example, Wnt-3a can induce self-renewal of hematopoietic stem cells, allowing expansion without further differentiation (6).
