The reverse transcriptase in plasma from leukaemic patients perfers the divalent cation Mn++ to Mg++ in the polymerase assay. The reverse is true for the enzyme from plasma of patients with breast cancer. This cation preference is analogous to the cation preference found in B- and C-type RNA-tumour viruses.
白血病患者血浆中的逆转录酶在聚合酶测定中更喜欢二价阳离子Mn++而非Mg++。乳腺癌患者血浆中的酶则相反。这种阳离子偏好类似于在B型和C型RNA肿瘤病毒中发现的阳离子偏好。
