Evagreen Dye Fluorescence Verification
Chia-Hsien Shih
Abstract
This protocol is to establish the relationship between Evagreen Dye fluorescent intensity and DNA concentration.
Steps
Preparation
Take 30µL
of 10µM ssDNA (T4 ligation primer) into a new eppendorf
Dilute 10µM ssDNA into 1µM :
Take 3µL
of 10µM ssDNA and 27µL
RNase-free water into a new eppendorf
Dilute 1µM ssDNA into 100nM :
Take 3µL
of 1µM ssDNA and 27µL
RNase-free water into a new eppendorf
Dilute 100nM ssDNA into 10nM :
Take 3µL
of 100nM ssDNA and 27µL
RNase-free water into a new eppendorf
Dilute 10nM ssDNA into 1nM :
Take 3µL
of 10nM ssDNA and 27µL
RNase-free water into a new eppendorf
Dilute 1nM ssDNA into 100pM :
Take 3µL
of 1nM ssDNA and 27µL
RNase-free water into a new eppendorf
Dilute 100pM ssDNA into 10pM :
Take 3µL
of 100pM ssDNA and 27µL
RNase-free water into a new eppendorf
Add 1.5µL
of 20X evagree dye into each eppendorf.
Measure
Respectively load 20µL
of 10µM,1µM, 100nM, 10nM, 1nM, 100pM and 10pM ssDNA into each well
Measure the fluorescence excitation and emission intensity
