Cân bằng lắng: một công cụ quý giá để nghiên cứu tương tác đồng nhất và dị nhất của protein hoặc protein và axit nucleic
Tóm tắt
Chúng tôi trình bày một cái nhìn tổng quan ngắn gọn về kinh nghiệm của mình trong việc phân tích độ affin và tỉ lệ phối trí của các tương tác tự liên kết và dị liên kết thông qua việc sử dụng kỹ thuật cân bằng lắng. Quy trình thu thập dữ liệu và quy trình phù hợp sử dụng các chương trình máy tính mà chúng tôi đã phát triển, Polymole và Virial, được sử dụng để đạt được những kết quả đáng tin cậy dưới cả điều kiện lý tưởng và không lý tưởng. Những dữ liệu này thu được từ các macromolecule quan trọng sinh học sẽ hữu ích trong việc hiểu các sự kiện sinh lý học như sự điều tiết tế bào.
