Immuno-affinity purification of heparinase.
The International Journal of Biochemistry
|January 1, 1985
Summary
Rabbit antibodies against heparinase enzyme were developed. These antibodies purified the enzyme effectively and surprisingly enhanced its activity, offering a novel purification method.
Area of Science:
- Biochemistry
- Enzymology
- Immunology
Background:
- Heparinase is an enzyme that degrades heparin.
- Purification of heparinase is essential for its study and application.
- Standard purification methods can be complex and time-consuming.
Purpose of the Study:
- To develop polyclonal IgG rabbit antibodies against purified heparinase from Flavobacterium heparinum.
- To utilize these antibodies for immuno-affinity purification of heparinase.
- To assess the purity of the immuno-affinity purified enzyme and its effect on enzyme activity.
Main Methods:
- Generation of polyclonal IgG rabbit antibodies against purified heparinase.
- Immuno-affinity chromatography using the prepared antibodies for heparinase purification.
- Comparison of purity with standard multi-step purification schemes.
- Assay of heparinase activity before and after antibody binding.
Main Results:
- Successfully prepared polyclonal IgG rabbit antibodies against heparinase.
- Demonstrated effective immuno-affinity purification of crude and partially purified heparinase.
- Achieved enzyme purity comparable to standard purification methods.
- Observed an increase in the activity of heparinase bound to the antibodies.
Conclusions:
- Immuno-affinity purification using specific antibodies is an efficient method for heparinase purification.
- The developed antibodies not only purify but also enhance the activity of heparinase.
- This approach offers a potentially simpler and more effective alternative to traditional purification techniques.
