Figure 1From: Analysis of transcribed human endogenous retrovirus W env loci clarifies the origin of multiple sclerosis-associated retrovirus envsequencesExpression of HERV-W env in human PBMC. RT-PCR using HERV-W env-specific primers was carried out on total RNA isolated from human PBMC which was subjected (+) or not (-) to reverse transcription. The expected size of the amplified HERV-W env fragment is ~640 bp. M, DNA size marker; H2O, PCR negative control.Back to article page
