SterileTechnique
Good sterile technique is the first and most important step in insuring consistent results when employing recombinant DNA and protein expression techniques. Sterile technique refers to procedures by which cultures may be manipulated without infecting the worker or contaminating the cultures or the laboratory environment.Because contaminating bacteria are ubiquitous and are found on fingertips, bench tops, etc., it is......阅读全文
