Human leukocyte interferon purified to homogeneity
Science (New York, N.Y.)
|December 22, 1978
Summary
Researchers purified a human interferon protein produced by leukocytes stimulated with Newcastle disease virus. The purified interferon showed a single peak of activity and a single protein band, indicating high purity.
Area of Science:
- Immunology
- Virology
- Biochemistry
Background:
- Human interferons are crucial cytokines involved in antiviral responses.
- Leukocytes are key immune cells that produce interferons upon viral stimulation.
- Newcastle disease virus is a potent inducer of interferon production.
Purpose of the Study:
- To purify and characterize a specific species of human interferon.
- To confirm the homogeneity of the purified interferon protein.
Main Methods:
- Human leukocytes were incubated with Newcastle disease virus.
- Interferon was purified to homogeneity using biochemical techniques.
- Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was employed for purity analysis.
Main Results:
- A specific species of human interferon was successfully purified.
- The purified interferon exhibited a single peak of biological activity.
- SDS-PAGE revealed a single protein band, confirming homogeneity.
Conclusions:
- The purification process yielded a highly pure human interferon protein.
- This purified interferon serves as a valuable reagent for further immunological and biochemical studies.
