Overview
To ascertain the efficacy of the method of DNA extraction and assess DNA sample concentration and purity before use in downstream applications.
Service Details
Samples are delivered to the CPGR on dry ice (RNA), at room temperature or on wet ice. An aliquot of the sample (1-2 µl) is removed and measured on the Nanodrop ND 1000 after blanking with DNAse and RNAse Free Water or eluent buffer provided with the DNA extraction kit. If the presence of contaminants, salts and/or inhibitors is suspected (260/230 ratios >1.5), ethanol precipitation will be performed to clean up the samples.
Service Deliverables
An analytical report will be provided detailing sample concentration and purity. If sample clean up (ethanol precipitation) is required, the steps taken will be included in the report. The final DNA sample will be returned to the client when and if necessary.
