The Histochemical Journal
|October 1, 1985
Summary
Lyophilized protein-gold complexes, including those with staphylococcal protein A, Helix pomatia lectin, and horseradish peroxidase, maintain their staining abilities after long-term storage. This study established optimal conditions for preserving these valuable biochemical reagents.
Area of Science:
- Biochemistry
- Materials Science
- Analytical Chemistry
Background:
- Protein-gold complexes are widely used in various biochemical and diagnostic applications.
- Preservation methods are crucial for maintaining the functionality and reliability of these complexes.
Purpose of the Study:
- To establish optimal conditions for the preservation of protein-gold complexes.
- To evaluate the long-term stability and functionality of preserved complexes.
Main Methods:
- Investigated conditions for dialysis, freezing, and lyophilization of protein-gold complexes.
- Assessed the staining properties of reconstituted lyophilized complexes after storage.
Main Results:
- Established reliable protocols for dialysis, freezing, and lyophilization.
- Lyophilized complexes demonstrated retained staining properties after several months of storage.
- Tested complexes included colloidal gold with staphylococcal protein A, Helix pomatia lectin, and horseradish peroxidase.
Conclusions:
- Lyophilization is an effective method for long-term preservation of protein-gold complexes.
- Preserved complexes maintain their functional integrity and staining capabilities.
- The established methods ensure the availability of stable protein-gold reagents for research and diagnostics.
