1. Protocol A Specimen Collection Storage and Transport Precaution All samples have to be treated as potentially infectious material 1 Specimen Collection and Sample Storage e Blood withdrawal causes injury of blood vessels arteries veins and capillaries e Only safe and sterile material should be used e For blood withdrawal appropriate disposables are available For the vein puncture too fine capillary needles should not be employed e Venous blood withdrawal should be carried out on the appropriate parts of the elbow bend the forearm or the back of the hand e Blood has to be withdrawn with standard specimen collection tubes red cap Sarstedt or equivalent tube of another manufacturer 5 10 ml EDTA blood should be withdrawn Precaution Samples of heparinised humans must not be used 2 Sample Storage e Whole blood should be separated into plasma and cellular components by centrifugation for 20 minutes at 800 1 600 x g within six hours The isolated plasma has to be transferred into sterile polypropylene tubes e The sensitivity of the assay can be reduced if you freeze the samples as a matter of routine or store them for a longer period of time e Virus encapsulated DNA is stable for days if stored at 4 C for weeks if stored at 20 C and even for months and years when stored at 70 C 3 Sample Transport e Sample material should be transported in a shatterproof leak proof transport container as a matter of prin2. and lipids 2800 mg dl and haemolytic samples do not influence the system Table 1 Volume of Ethanol to be added to Binding Buffer Il and Wash Buffer Volume Provided Ethanol 96 100 Volume to Add Binding Solution II Wash Solution e An HSV 2 Isolation Control soC is supplied This allows the user to control the DNA isolation procedure For this assay add the HSV 2 Isolation Control soC to the lysate during the isolation procedure o The HSV 2 Isolation Control soC must not be added to the sample material directly o Do not freeze and thaw the HSV 2 Isolation Control soC more than 2 times o The HSV 2 Isolation Control soC must be kept on ice at all times during the isolation procedure Final Volume 10 mL 15 mL 1 Add 200 uL of Binding Solution I for every 0 5 mL of Plasma Serum sample Mix well by inversion 2 Transfer the 700 uL Plasma Binding Solution mixture into the provided spin column Vortex for 15 seconds 3 Centrifuge for 1 minute at 10 000 rom and discard the flowthrough 4 Add 30 uL of both Proteinase K and Pronase to column Vortex for 10 seconds 5 Incubate the mixture at 60 C for 20 minutes 6 After the 20 minute incubation add 260 uL Binding Solution Il 7 Add 15 uL HSV 2 Isolation Control IlsoC to the lysate mix well by vortexing 8 Centrifuge for 1 minute at 10 000 rpm Do Not discard the flow through 9 Re Load the flowthrough back to the column and centri
