Src Blocking Peptide #1235
Description
This peptide is used to specifically block Src Antibody #2108 and Src (36D10) Rabbit mAb #2109 reactivity.
Quality Control
The quality of the peptide was evaluated by reversed-phase HPLC and by mass spectrometry. The peptide blocks Src Antibody #2108 and Src (36D10) Rabbit mAb #2109 signal in immunohistochemistry.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human breast carcinoma, using Src Antibody #2108 in the presence of control peptide (left) or Src Blocking Peptide (right).
Applications
Use as a blocking reagent to evaluate the specificity of antibody reactivity in immunohistochemistry protocols.
Directions for Use
For immunohistochemistry, add twice the volume of peptide as volume of antibody used in 100 µl total volume. Incubate for a minimum of 30 minutes prior to adding the entire volume to the slide. Recommended antibody dilutions can be found on the Src Antibody #2108 and Src (36D10) Rabbit mAb #2109 data sheets.
Background
The Src family of protein tyrosine kinases (including Src, Lyn, Fyn, Yes, Lck, Blk and Hck) are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. Phosphorylation of Tyr416 in the activation loop of the kinase domain by Csk upregulates enzyme activity, whereas phosphorylation of Tyr527 in the carboxy-terminal tail renders the enzyme less active (2).
