At first, ExoSAP-IT is diluted by 5% using sterilized distilled water (ExoSAP-IT 0.2 µL + Sterilized distilled water 3.8 µL / 1 sample ). ↓ The diluted ExoSAP-IT 4 µL is added directly to the PCR product 9 µL.
↓ add 125mM EDTA(pH7.5-8.0) 1 µL, 3M sodium acetate 1 µL ↓ add 100% ethanol (-20℃) 25 µL ↓ vortex 2 min ↓ incubate at room temperature for 15 min ↓ centrifuge at 4000rpm for 30 min ( 4℃) ↓ centrifuge at 1000rpm for 1 sec (4℃) upside down ↓ The pellet is washed in cold 70% ethanol 35 µL. ↓ centrifuge at 4000rpm for 10 min (4℃) ↓ centrifuge at 1000rpm for 1 sec (4℃) upside down ↓3min dry up
