SMAD4, also called SMAD family member 4, Mothers against decapentaplegic homolog 4, or DPC4 (Deleted in Pancreatic Cancer-4) is a highly conserved protein present in all metazoans. It belongs to the SMAD family of transcription factor Proteins, which act as mediators of TGF-β signal transduction. The TGFβ family of cytokines regulates critical processes during the lifecycle of metazoans, with important roles during embryo development, tissue homeostasis, regeneration, and immune regulation.
As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

The recovery of Human Smad4 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
Sample Type | Range(%) | Average Recovery(%) |
Tissue Homogenates(n=8) | 84-101 | 95 |
Cell Lysates(n=8) | 92-105 | 102 |
Samples were spiked with high concentrations of Human Smad4 and diluted with Universal Diluent to produce samples with values within the range of the assay.
