Anti-PTEN Antibody, CT, clone A2b1

32160702

NA.41

Specifically recognizes PTEN*, a tumor suppressor protein located on human chromosome 10 (Steck, ′97; Li, ′97; Rhei, ′97) that is often mutated in various types of advanced cancers (Rhei, ′97). The PTEN protein exhibits protein phosphatase activity (Myers, ′97) and can suppress the growth of glioma cells (Furnari, ′97). The antibody recognizes human and mouse PTEN and is specific for the C-terminus. Other species not tested. Reactivity with human fibroblasts, breast epithelial and lung cancer cell lines has been confirmed by western blot, and antibody specificity has been confirmed by peptide blocking studies.

*PTEN is covered under U.S. patents 6,262,242, 6,482,795 and U.S. patent application 10/299,003.

Anti-PTEN was generated by immunization with a 10 amino acid peptide corresponding to amino acids 387-400 near the C-terminus of human PTEN.
Epitope: C-terminus

Anti-PTEN Antibody, C-terminus, clone A2b1 is an antibody against PTEN for use in IC, IH, IP & WB.

Immunocytochemistry

Immunohistochemistry: 1:20 to 1:50 for acetone-fixed, fresh frozen tissue. Not effective for paraffin sections.

Immunoprecipitation 1:10 to 1:20

Protocol for immunohistochemistry of frozen tissue sections on glass slides.

1. Fix sections for 5 minutes with cold acetone.

2. Air dry

3. Wash sections with PBS

4. Add blocking solution (horse serum) for 20 minutes

5. Add diluted PTEN antibody and incubate for 1 hour at room temperature.

6. Wash with PBS

7. Add biotinylated secondary antibody (horse anti-mouse, or equivalent).

8. Incubate for 30 minutes at room temperature.

9. Wash with PBS

10. Detect with ABC (Avidin-Peroxidase-Complex) or equivalent.

11. Wash with PBS

12. Develop with DAB substrate.

13. Hematoxylin dye may be used as a counterstain for visualizing nuclei.Breast tumor tissue gives good staining. Prostate tissue does not stain.Optimal working dilutions must be determined by end user.
