The Purification and Concentration of Diphtheria Toxoid
By precipitation with acetone at 4 degrees C. a refined diphtheria toxoid was obtained as a dry powder, readily soluble in aqueous solutions. The powder itself appears to be stable. When dissolved in half the original volume of physiological salt solution, the toxoid remained stable, in the cold room, for a period of 7 months. Only toxoids should be used which have been completely detoxified by...
متن کاملPreparation and Evaluation of Diphtheria Toxoid-Containing Microspheres
Preparation of chitosan (CS) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low CS molecular weight (MW) was investigated in this study. Diphtheria toxoid (DT) was used as a model antigen. The emulsion-solidification method was adopted for microencapsulation of DT. In the first step, following the purification of semi-crude DT by the ion-exchan...

متن کاملOPTIMIZATION OF DIPHTHERIA TOXOID PRECIPITATION BY USING SATURATED AMMONIUM SULPHATE IN ORDER TO IMPROVE DIPHTHERIA VACCINE
سابقه و هدف: کورینه باکتریوم دیفتریه باکتری هوازی و بیهوازی اختیاری است. مهمترین گونه از خانواده کورینه باکتریاها، عامل بیماری دیفتری است که به وسیله توکسین خود، بیماری دیفتری را ایجاد میکند. آمونیم سولفات نمکی معدنی است که از آن برای ترسیب و خالصسازی پروتئین ها استفاده میشود که با افزایش مقدار نمک حلالیت پروتئینی کم شده و پروتئین ها به واسطه قطعه های هیدروفوب خود، بههم پیوسته و رسو...
متن کاملStudies on Antigenicity
The enzymatic degradation of fluorescein conjugates of poly-L-lysine, poly-D-lysine, and exhaustively succinylated poly-L-lysine by aqueous extracts of spleens from "responder" (guinea pigs which can develop immune responses to hapten-poly-L-lysine conjugates) and "non-responder" guinea pigs was investigated. The in vivo degradation of H(3)-tagged dinitrophenyl conjugates of these synthetic pol...
