Monoclonal antibody highly sensitive for the detection of ras p21 in immunoblotting analysis

Area of Science:

• Molecular Biology
• Immunology
• Oncology

Background:

• Ras proteins (p21) are critical regulators of cellular signaling pathways.
• Aberrant ras signaling is implicated in various human cancers.
• Sensitive detection methods for ras p21 are essential for cancer research.

Purpose of the Study:

• To produce and characterize novel murine monoclonal antibodies reactive with ras p21.
• To evaluate the utility of these antibodies for detecting ras p21 in biological samples.

Main Methods:

• Production of murine monoclonal antibodies using recombinant c-Ha-ras p21 as an immunogen.
• Immunoblotting analysis to assess antibody sensitivity and specificity.
• Detection of ras p21 in cell and tissue lysates, including those with point-mutationally activated ras.

Main Results:

• Four monoclonal antibodies (NCC-RAS-001, -004, -005, -017) were successfully generated.
• Antibody NCC-RAS-004 demonstrated high sensitivity in immunoblotting.
• NCC-RAS-004 enabled semiquantitative detection of c-Ha-, c-Ki-, and N-ras p21.
• Detection of abnormal ras p21 mobility in cells with activated ras mutations was achieved.

Conclusions:

• Monoclonal antibody NCC-RAS-004 is a highly sensitive tool for detecting ras p21 proteins.
• This antibody facilitates the semiquantitative analysis of ras p21 in various cellular and tissue contexts.
• The developed antibodies can aid in the study of ras signaling in normal and cancerous conditions.
