Kollagenas Förberedelser Väg ut kollagenas i en 50 ml konisk och lägga isolering buffert för att göra den slutliga koncentrationen, som framgår av tabellen nedan. Lös kollagenas genom att vortexa. (12 möss + 2 extra möss = 14 möss x 5 ml / mus = 70 ml totalt kollagenas lösning) (70 ml x 0,5 mg / ml eller 0,3 mg / ml = 35 mg eller 21 mg av kollagenas P totalt) <table style="BORDER-RIGHT: #ddd 1px solid; BORDER-TOP: #ddd 1px soli…
