SSC buffer is named after its ingredients Saline (sodium chloride) and Sodium Citrate. It is used as a buffer for blotting, hybridisation, and stringency washes in Northern and Southern blots as well as DNA microarray.
1x SSC buffer
- 150mM NaCl
- 15mM sodium citrate
20x SSC
- 800ml dH2O (RNase free if required)
- 175.3g NaCl (3M)
- 88.2g trisodium citrate (NaCit; 300mM; e.g. S4641)
- adjust the pH to 7.0 with a few drops of 1M HCl
- adjust the volume to 1L with dH2O
- sterilize by autoclaving
using stock solutions
- 3M NaCl
- 300 mM sodium citrate, pH 7.0
protocols using SSC
- Dahlquist:DNA Microarray Protocol
- Endy:Northern Blot, 32P End-Labeled Probes
- 20.109(S07): cDNA synthesis and microarray
- 20.109(F08): Mod 2 Day 7 cDNA synthesis and microarray
