The electrophoresis buffers maintain consistent pH levels during DNA, RNA, and other protein separation. Providing ions that transfer the applied current, the low charge solutions facilitate different molecular sizes to travel at various rates for analyses. Offering additional protection to proteins, the preparative substances prevent degradation for guaranteed sample viability and accurate testing. Available in various molecular weights, the best electrophoresis buffer can be selected based on the specific macromolecules being handled.

SSC buffer, 20X concentrate, pH 7,0
Supplier: Rockland Immunochemicals
Saline-sodium citrate (SSC) buffer is most commonly used as a buffer for the hybridisation process and washing in experiments where spcies of nucleic or ribonucleic acid are to be matched to complimentary sequences (such as Southern and Nouthern blotting, in situ hybridisation, or DNA microarrays). SSC is used to help control the stringency of hybridisation in these steps.
