General description

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with P3X63 Ag8.653 mouse myeloma cells. Recognizes the ~21 kDa c-H-Ras protein.
Recognizes the ~21 kDa c-H-Ras protein in normal skin tissue and Rat1 cells. Does not react with c-K-Ras or c-N-Ras p21. A doublet may be seen due to farnesylation.
This Anti-c-H-Ras (Ab-1) Mouse mAb (F235-1.7.1) is validated for use in Frozen Sections, Immunoblotting, IF, IP, Paraffin Sections for the detection of c-H-Ras (Ab-1).

Immunogen

Epitope: within amino acids 54-188
recombinant p21 Ras

Application

Frozen Sections (5 µg/ml)

Immunoblotting (10 µg/ml)

Immunofluorescence (2.5 µg/ml)

Immunoprecipitation (5 µg/ml)

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

Packaging

Please refer to vial label for lot-specific concentration.

Warning

Toxicity: Standard Handling (A)

Physical form

In 50 mM sodium phosphate buffer, 0.2% gelatin, pH 7.4.

Analysis Note

Positive Control
Normal skin tissue or ras 1 cells

Other Notes

For immunoprecipitation, use 5 µg of Cat. No. OP23 per sample with 45 µl protein G plus agarose. The level of expression of p21Ras is variable in different tissues. For this reason, we recommend a concentration step prior to immunoblotting analysis to obtain optimal results. A doublet may be seen due to farnysylation. Recognizes c-H-Ras and, weakly, v-H-Ras; does not recognize either c-K-Ras or c-N-Ras p21s under the conditions tested. Antibody should be titrated for optimal results in individual systems.

Cancer stem cells (CSCs) have tumour initiation, self-renewal, and long-term tumour repopulation properties, and it is postulated that differentiated somatic cells can be reprogrammed to CSCs by oncogenic signals. We previously showed that oncogenic HRASV12 conferred tumour initiation capacity in

Chemically induced skin carcinomas in mice are a paradigm for epithelial neoplasia, where oncogenic ras mutations precede p53 and INK4a/ARF mutations during the progression toward malignancy. To explore the biological basis for these genetic interactions, we studied cellular responses to

The p53 tumor suppressor promotes cell cycle arrest or apoptosis in response to stress. Previous work suggests that the promyelocytic leukemia gene (PML) can act upstream of p53 to enhance transcription of p53 targets by recruiting p53 to nuclear bodies

Interleukin-11 (IL-11), which belongs to a class of IL6-type cytokines, plays an important role in inflammation, motility and invasion in cancer. The ras mutation is frequently found in human cancer, but little is known regarding the transcriptional activation of the
