Hybridization and Immobilization
Chia-Hsien Shih
Abstract
This protocol is to assemble GotCha with circular probe, immobilization probe and magnetic beads.
Steps
Preparation
Dilute immobilization probe into 10µM
Protocol of Hybridization
Add 4.5µL of 1µM circular probe
Add 9µLof 10X 7.4 PBS buffer
Add 0.9µL of 10µM immobilization probe
Add 75.6µL RNase-free water
Vortex slightly and spin down
Heated to 90°C for 0h 0m 30s then cool down to 90Room temperature and keep for 0h 30m 0s
Protocol of Immobilization
Take 22.5µL of 10mg/ml magnetic beads into a eppendorf
Vortex then spin down in Centrifuge 15000rpm
Carefully take the eppendorf onto the DynaMag and wait for 0h 1m 0s to collect the beads
Wash beads with 1X PBS for three times. Make sure that eppendorf should put on DynaMag when removing supernatant.
Add 90µL of hybridization solution into the eppendorf with dry beads
Incubate at 90Room temperature for 0h 30m 0s, then spindown in Centrifuge15000rpm
Carefully take the eppendorf onto the DynaMag and wait for 0h 1m 0s to collect the beads
Wash beads with 1X PBS for three times. Make sure that eppendorf should put on DynaMag when removing supernatant.
Preserve the functional beads in 90µL 1X PBS
