| Phos binding reagent Biotin LC
An equivalent to Phos-tag Biotin. Detection of phosphorylated proteins |
Sample solution is provided at 25 µL, 10mM.
Phos binding reagent Biotin provides a sensitive method for detection of phosphorylated proteins on a PVDF membrane. This method needs streptavidin-conjugated horseradish (HRP) and chemiluminescent detection reagent.
Protein phosphorylation is an important covalent post-translational modification that can alter the structural conformation of a protein, which then regulates the function, location and specific binding of the target protein. Many cellular processes are regulated by the reversible phosphorylation of proteins and 30% of the proteins are likely to be phosphorylated at some point during their existence.
The determination of the phosphorylation state of proteins is important for defining protein kinase substrates and revealing the activation state of signal transduction pathways. Methods for determining the phosphorylation status of proteins are thus have important implications in the understanding of diverse biological and pathophysiological processes, such as signal transduction pathways, cancer and other diseases.
Phos binding reagents are specific and selective phosphate-binding reagents, and exhibit preferential ionic interactions with phosphorylated ions on phosphorylated proteins or peptides at neutral pH. Phos binding reagent is a dinuclear metal (Zn2+ or Mg2+) complex.
Phos binding reagent Biotin LC is a specific reagent for detection of phosphorylated proteins using Western Blot and can instead of the specific phosphorylated antibodies.

1. Highly sensitive detection of phosphorylated proteins.
2. The binding specificity of Phos binding reagent Biotin is independent on amino acid and sequence context.
3. Followed by antibody reprobing and MS analysis are applicable.
4. The procedure is almost the same as that with an HRP-conjugated antibody.
