Rat monoclonal antibody specific for septin 9

Area of Science:

• Cell Biology
• Molecular Biology
• Immunology

Background:

• The septin family of GTPase proteins plays crucial roles in cell division, cytoskeletal organization, and membrane remodeling.
• Septin 9 (SEPT9), a member of the septin family, has been linked to tumorigenesis.

Purpose of the Study:

• To generate and characterize a monoclonal antibody (MAb) specifically targeting SEPT9.
• To evaluate the utility of the MAb for detecting SEPT9 expression and analyzing its function.

Main Methods:

• Production of a monoclonal antibody (MAb 7B5) through hybridoma technology (mouse myeloma cells fused with lymph node cells from an immunized rat).
• Validation of MAb 7B5 specificity for SEPT9 using immunoblotting on various cell extracts.
• Application of MAb 7B5 in immunostaining to visualize SEPT9 localization within cells.

Main Results:

• The MAb 7B5 was successfully produced and demonstrated specific recognition of SEPT9 via immunoblotting.
• Immunostaining with MAb 7B5 revealed a filamentous SEPT9 pattern localized near the plasma membrane.

Conclusions:

• The MAb 7B5 is a specific and valuable tool for detecting SEPT9.
• This antibody can be utilized in immunoblotting and immunostaining across diverse cell types and tissues.
• MAb 7B5 will aid in quantifying SEPT9 expression levels and advancing the understanding of its biological functions, particularly in tumorigenesis research.
