Silica Spin Column

Silica Spin Column Mini Spin Columns for DNA/RNA extraction.Silica membrane based spin column.Compatible with Qiagen's and Invitrogen’s buffer.Buffer recipe provided for plasmid Miniprep, Gel extraction and PCR clean up. High qualify for DNA purification and has been used extensively in house application and by many academic labs. Economical for large sample process.Quality of Certificate Test methods:1. Extract plasmid by N5005, test the DNA adsorption rate and purity of silica spin column.2. Collect the overnight cultured bacteria 150ml. The bacteria contains pUC19-1 plasmid.3. Extract the plasmid according to N1011(High Purity Plasmid Miniprep Kit) process.4. Test the OD value of the extracted plasmid and make agarose gel electrophoresis examination. Test results: 1. OD Value, rate and plasmid concentration Sample Read 260 Raw 280 Raw 320 Raw 260 280 260/280 ng/ul 1 0.395 0.244 0.055 0.340 0.189 1.800 240.462 2 0.391 0.243 0.058 0.336 0.187 1.796 236.489 2.
