Study on Bacterial Endotoxin Test Method of Boric Acid Rinse / 中国药房

OBJECTIVE:To establish a method for bacterial endotoxin test of Boric acid rinse.METHODS:According to appendix volumeⅡof Chinese Pharmacopoeia(2005 edition),the tachypleus amebocyte lysate(TAL)method was applied for the pre-inference test and interfence test to investigate non-inference concentration,pH value and sensitivity of TAL.RESULTS:Boric acid did not interfere with TAL and the reaction of bacterial endotoxin at 2 times diluted concentration with pH value adjusted above 6.The sensitivity 0.25 EU?mL-1 of TAL was available.CONCLUSION:The TAL method can control the limit of bacterial endotoxins in Boric acid rinse.
