exogenous variable 中文意思是什麼
exogenous variable
解釋
局外變量-
The env protein deduced from env gene encodes the hydrophilic surface protein ( su ) and the hydrophobic transmembrane domain ( tm ) that determine the specific interaction between virus particles and cell surface receptors during retroviral entry. the su of retroviruses is a highly variable genetic element, containing receptor binding sites and major antigenic determinants. exjsrv - specific dna probes were derived. by using these dna probes in tissue hybridization. we successfully identified jsrv mrna expression and proviruses dna in sheep lung tissues infected with jsrv and control group has no postive signals, validating the use of exogenous virus - specific dna probes in the analysis of oncogenic proviral integration sites and identification of integrated exogenous proviral sequences
用地高辛隨機引物法標記exjsrv特異的env片段，制備探針，原位雜交檢測spa肺組織中的rna及前病毒dna ，結果表明spa患羊肺組織內有jsrvenv基因mrna的表達，同時也檢測到了前病毒dna ，而相應的陰性對照卻無陽性信號，證實外源性病毒特異的dna探針在致瘤性前病毒的整合位點和整合的外源性前病毒的檢測中具有可信度。 -
