Purified rat monoclonal antibody generated by immunizing Sprague Dawlay rats with the specified immunogen and fusing splenocytes with Y3Ag1.2.3 rat myeloma cells. Recognizes the ~21 kDa Ras protein (see comments).

Recognizes both phosphorylated and nonphosphorylated forms of v-H-Ras, and v-K-Ras in SW480 and Y1 cells and normal skin tissue. Also recognizes H, K, and N-Ras human translated products.

This Anti-v-H-Ras (Ab-1) Rat mAb (Y13-259) is validated for use in Frozen Sections, Immunoblotting, IF, IP, Paraffin Sections, Neutralization Studies for the detection of v-H-Ras (Ab-1).

Epitope: within amino acids 62-76

recombinant p21 Ras

Frozen Sections (5 µg/ml)

Immunoblotting (2.5 µg/ml, colormetric or chemiluminescence)

Immunofluorescence (2.5 µg/ml)

Immunoprecipitation (use Cat. No. OP01A or 1 µg antibody per sample)

Paraffin Sections (5 µg/ml, saponin or pepsin pre-treatment required)

Neutralization Studies (see application references)

Please refer to vial label for lot-specific concentration.

Toxicity: Standard Handling (A)

In 0.05 M sodium phosphate buffer, 0.2% gelatin.

Positive Control
SW480 or Y1 cells or normal skin tissue

Broadly reactive with the phosphorylated and non-phosphorylated forms of v-H-Ras and v-K-Ras (see application references) and recognizes the p21 translational products of the H-, K-, and N-ras human genes (see application references). This antibody does not cross-react with rap. Neutralizes the biological and biochemical activities of H-, K-, and N-ras p21 of vertebrates by binding to residues Glu-63, Ser-65, Ala-66, Met-67, Gln-70, and Arg-73 (see application references). 15 µl v-H-ras (Ab-1) agarose conjugate (Cat. No. OP01A) is recommended to be used as an immunoconcentrator prior to immunoblot analysis of p21^ras with another antibody. To immunoprecipitate with the unconjugated antibody, use Protein A with a rabbit anti-rat IgG or Protein G PLUS with a goat anti-rat IgG. Protein A alone will not immunoprecipitate rat IgG. A doublet may be detected corresponding to ras protein with and without farnesyl group. Antibody should be titrated for optimal results in individual systems.
