近年來的研究証明,病毒的化学本質主要是核蛋白,而其中的核酸又是决定病毒传染与生长繁殖的物質基础。因此,当病毒生長繁殖时,必須攝取大量的磷。許多研究家曾用同位素磷(P~(32))進行研究,証明多种病毒(如流行性感冒病毒,脊髓灰質炎病毒等)在含有放射磷的培養环境中生长繁殖 Recent studies have shown that the chemical nature of the virus is mainly nuclear proteins, and the nucleic acids therein are the material basis for virus infection and growth. Therefore, when the virus grows and reproduces, a large amount of phosphorus must be taken. Many researchers have conducted studies using isotope phosphorus (P32) and have shown that many viruses (eg influenza virus, poliovirus, etc.) grow and multiply in culture environments containing radioactive phosphorus.
