From: Proteome analysis of the hyaluronic acid-producing bacterium, Streptococcus zooepidemicus
2-DE gels of S. zooepidemicus . Proteins were separated using pH gradient 4–7 on 7 cm 12% polyacrylamide gels. Following separation, proteins were stained with silver nitrate. When HA was not removed, poor quality, streaky gels were obtained (A); digestion of HA prior to protein extraction resulted in high quality, streak-free gels (B).
