Human Protein Wnt-3a ELISA: A Key Tool in Cellular Signaling and Disease Research

The Human Protein Wnt-3a ELISA Kit is a precise and sensitive immunoassay designed for quantifying Wnt-3a levels in human biological samples. This kit is critical for exploring the Wnt signaling pathway, which plays a pivotal role in cell development, differentiation, and diseases such as cancer, osteoporosis, and neurodegenerative disorders.

What is Wnt-3a?

Wnt-3a is a secreted glycoprotein that acts as a key ligand in the Wnt signaling pathway. This pathway regulates essential cellular processes like proliferation, migration, and stem cell maintenance. Dysregulation of Wnt-3a expression is associated with tumorigenesis, bone disorders, and developmental anomalies. To learn more about the Wnt signaling pathway, visit NCBI and NHGRI.
