1 Stock number stamps contain movable bands with the numbers 0 - 9. 2  Choose between a sturdy metal core frame or sleek, economical plastic frame number stamp.
The channel has a large diameter of 0.8x1.1nm, and is non-selective for small ions. However, it has an upper exclusion size limit corresponding to molecular weights of about 600 Dalton of permeants. Because most metabolites have molecular weights lower than 600 Da and have been shown to pass through porin channels, porins are called general diffusion pores.
Multiplex PCR with amplicons that have similar size: how can I check if all the fragments have been amplified? I want to amplifiy 10 amplicons by multiplex PCR. They should be sequenced on Ion Torrent so they are 180-210 bp long. The amplicons differ for only few bp each other. Standard agarose gel does not have enough resolution. We don't have 2100 Bioanalyzer in the lab. How can check fast and easily if I have all my PCR products? Any ideas?
