The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Purity70 - 90% by HPLC.
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions. - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer. - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent. - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised. - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

MAD homolog 6

Mothers against DPP homolog 6
SMAD family member 6
SMAD mothers against DPP homolog 6
FunctionAntagonist of signaling by TGF-beta (transforming growth factor) type 1 receptor superfamily members; has been shown to inhibit selectively BMP (bone morphogenetic proteins) signaling by competing with the co-SMAD SMAD4 for receptor-activated SMAD1. SMAD6 is an inhibitory SMAD (I-SMAD) or antagonistic SMAD. Binds to regulatory elements in target promoter regions.
Tissue specificityUbiquitous in various organs, with higher levels in lung. Isoform B is up-regulated in diseased heart tissue.
Sequence similaritiesBelongs to the dwarfin/SMAD family. Contains 1 MH1 (MAD homology 1) domain. Contains 1 MH2 (MAD homology 2) domain.
Post-translational modificationsPhosphorylated by BMP type 1 receptor kinase and by PRKX. Ubiquitinated by WWP1.
