| 摘要 |
The invention relates to a process for obtaining purified transfer factor, the transfer factor thus obtained, and uses thereof. The transfer factor is obtained via filtering a sample to remove proteins weighing less than 15 kilodaltons, followed by separation of the transfer factor via interaction with an antigen to which it is specific. Following separation of the complex, the transfer factor is subjected to reversed phase high performance liquid chromatography and then gel filtration high performance liquid chromatography. The resulting transfer factor is antigen specific, has a molecular weight of from about 4900 to about 5500 daltons, affects transfer of a delayed type cell mediated immune response to an antigen, but does not affect antibody mediated response. |
