[Recombinant human brain myelin basic protein and its antibody].

Area of Science:

• Molecular Biology
• Immunology
• Biotechnology

Background:

• The detection of specific proteins is crucial for biological research and diagnostics.
• Developing efficient methods for producing recombinant proteins and antibodies is essential for advancing these fields.

Purpose of the Study:

• To construct a recombinant expression vector for human brain MBP.
• To express and characterize the fusion protein in E. coli.
• To generate and validate specific antibodies against MBP.

Main Methods:

• Gene cloning and vector construction using restriction enzymes (EcoR I, Sal I).
• Bacterial transformation (E. coli) and induction with IPTG.
• SDS-PAGE, Western blotting, immuno-dot blot, and ELISA for protein analysis.
• Antibody production in New Zealand rabbits via immunization with purified MBP.

Main Results:

• A recombinant vector p5TMP was successfully constructed and transformed into E. coli.
• A 42 KDa fusion protein was expressed and detected in transformed E. coli lysates.
• The fusion protein showed specific reactivity with anti-MBP antibodies.
• High expression level of MBP (414.6 mg/L) was achieved and quantified.
• Antibodies generated in rabbits demonstrated specific reactivity to MBP with a titer of 1:16.

Conclusions:

• The study successfully established a method for expressing a human brain MBP fusion protein in E. coli.
• The generated antibodies are specific to MBP, indicating their potential for diagnostic and research applications.
