Summary
This study presents a simple affinity chromatography method using anti-interferon antibodies to purify interferon. This technique efficiently isolates highly pure interferon, regardless of the starting material
Area of Science:
- Biochemistry
- Immunology
- Protein Purification
Background:
- Interferons (IFs) are crucial proteins in the immune response.
- Efficient purification of IFs is essential for research and therapeutic applications.
- Existing purification methods can be complex and time-consuming.
Purpose of the Study:
- To develop a streamlined, one-step purification protocol for mouse fibroblast interferon.
- To utilize anti-interferon antibodies immobilized on Sepharose for immunoadsorption.
- To assess the efficiency and capacity of the developed purification method.
Main Methods:
- Covalent binding of antibodies against mouse fibroblast interferon to activated CNBr-Sepharose 4B.
- Employing affinity chromatography for interferon purification.
- Analyzing purified interferon using polyacrylamide gel electrophoresis.
Main Results:
- A high binding capacity of 125,800 units per 4.8 ml of immunoadsorbent gel was achieved for mouse fibroblast interferon.
- Similar binding capacity was observed for mouse leukocyte interferon, with lower capacity for serum interferon.
- Electrophoretic profiles of purified interferon retained a similar shape to the unpurified material.
- The purification efficiency was independent of the starting material's volume, activity, or purity.
Conclusions:
- A one-step affinity chromatography procedure provides a highly efficient method for interferon purification.
- The developed immunoadsorbent demonstrates significant capacity and robustness.
- This method offers a simplified approach to obtaining pure interferon preparations for further study.
