Tissue distribution of hsp65 message. The presence of hsp65 message was evaluated in different tissue samples collected 48 hours (a) and 7 days (b) after intramuscular injection of 50 ug of pVAXhsp65. Total RNA (10 ug) isolated from each tissue was treated with DNase and subjected to RT-PCR amplification with specific primers. β-actin was amplified as an RNA quality control. All RT-PCR products were analysed by agarose gel electrophoresis and visualized by ethidium bromide staining. Similar results were observed in two animals analysed for each period. No products were seen (hsp65 and β-actin) when total RNA was subjected to PCR amplification in the absence of a previous reverse transcription.
