Growth phase dependence of invertase mRNA levels in yeast.

Aqueous Two-phase Extraction of Invertase from Baker’s Yeast

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Purification of the Internal Invertase of Yeast*

Most of the studies on yeast invertase have been concerned only with the external enzyme (a mannan protein which is localized in the cell wall), but recently it has been reported that the invertase inside the cytoplasmic membrane is a smaller form. This paper presents a comparative study of the distribution of invertase isozymes in two stains of yeast and, after the selection of the best condit...

Preparation of Highly Active Yeast Invertase*

In some preliminary experiments it was found that certain yeast invertase preparations which had been variously purified by adsorption to kaolin and alumina in accordance with the Willstiitter procedures (1) were soluble in saturated aqueous solutions of ammoniym sulfate. This solubility of the enzyme is interesting for two reasons. In the first place, saturated aqueous solution of ammonium sul...
