Eosin-B에 의한 rat 난모세포의 생존성 검사

Assessing the Viability of Rat Oocyte by Use of Eosin B

Eosin B의 사용에 의한 rat 난모세포의 생존성 및 발달가능성을 검사하였다. 염료는 Brinster's Medium for Ovum Culture puls glucose (BMOC)-2 medium ml당 eosin B 1.0mg을 함유하는 stock solution으로 준비하였다. 난모세포연구를 위하여 BMOC로 stock solution을 희석하여 만든 3가지의 염료농도들이 선택되었다 : 0.12mM, 0.60mM, 1.20mM. 난소세포들로부터 난모세포들을 채취하고, 보존기간 및 열 처리의 다양한 조건하에서 eosin B를 사용한 dye exclusion assay로 검사하였다. 생존한 난모세포는 eosin B를 배척하고, 사멸한 세포는 eosin B를 배척하지 않는 것으로 제시되었다.

The viability and developmental potential of rat oocyte was assessed by the use of eosin B. Dye was prepared as a stock solution to contain 1.0 mg eosin B per ml of Brinster's Medium for Ovum Culture plus glucose (BMOC) -2 medium. Three dye concentrations were selected for the Oocytes from rat ovarian follicles were collected and assessed under various conditions of heat oocyte studies by dilution of the stock solution with BMOC: 0.12mM, 0.60mM and 1.20mM. treatment and preservation duration by dye exc¬lusion assay using eosin B. It is suggested that live oocyte excludes eosin B whereas dead oocyte does not.
