An efficient and cost-effective method for purification of

Feb 05, 2019 · The final optimized protocol was tested to determine how increased sample volume affects nucleic acid recovery (Fig 3A, S2–S5 Appendices). As Fig 3B shows, increasing the volume 10-fold and 100-fold (from 250μl to 2.5ml and 25ml) improved actin Ct values by 2.5 and 5.2 Ct values, respectively. This linear improvement indicates that volumes

200ng of sample was required in a 10ul volume and so I had to use 1.2ul of sample with 4.8ul of sterile water, 4ul of bigdye with 1ul of primer for a total volume of 10ul. Concentration desired = (20ng/ul (200ng/10ul) * 10ul of final volume)/ 161.18ng/ul of sample

What will be the effect of using less than optimal volume of

I work with very less volume of sample 10-20 ul, as that is the amount of tears we can collect. Increasing sample volume requires multiple visits by the participants for just one assay. So, is there a way that ELISAs could be done with less than the required sample volume?
