永生化人顆粒細胞(HGL5)Immortalized Human Granulosa Cells (HGL5) | 貨號T0650
產品介紹: 卵巢顆粒細胞(Human ovarian granulosa cells , HGL5)是雌激素(estrogen)和孕酮產生的部位,使其成為研究類固醇生物合成(steroid biosynthesis),類固醇代謝酶(steroid-metabolizing enzymes),特定生長因子(growth factors)和促性腺激素(gonadotropins)的關鍵。永生化人顆粒細胞(Human ovarian granulosa cells , HGL5)表現出與原代卵巢顆粒細胞(primary ovarian granulosa cells)一致的品質; 這包括響應蛋白激酶-A活化(protein kinase-A activation)的細胞回縮(cell retraction),產生黃體酮(progesterone) 和雌二醇(estradiol)的能力,以及雌二醇(estradiol)產生的酶,P450arom。 所有這些特徵使得永生化人顆粒細胞株(Immortalized Human Granulosa Cell Line)成為研究與類固醇生物合成和代謝相關的機制的有吸引力的模型,以及其他途徑。

| Description | Human ovarian granulosa cells are the sites of estrogen and progesterone production, making them critical in studying steroid biosynthesis, steroid-metabolizing enzymes, particular growth factors, and gonadotropins. The Immortalized Human Granulosa Cells (HGL5) exhibits qualities consistent with primary ovarian granulosa cells; this includes cell retraction in response to protein kinase-A activation, the ability to produce progesterone and estradiol, and the enzyme integral to estradiol production, P450arom. All of these characteristics make the Immortalized Human Granulosa Cell Line an attractive model to study mechanisms relating to steroid biosynthesis and metabolism, in addition to other pathways. |

Abmgood不朽化系列商品 (immortalized reagenet) Ready-to-use
Abmgood公司於人類與老鼠不朽之細胞株上,具有幾十年的實驗經驗;提供一系列不朽 (immortalized)化之細胞株、及不朽化之試劑商品。ready-to-use定量好之retrovirus、lentiviru、 adenovirus,可直接加於細胞中進行感染表現;病毒液包括有SV40重組病毒、EBV重組病毒、hTERT病毒液、Myc基因病毒液、p53基因病毒液、Rb基因病毒液、Ras基因病毒液。提供106及109兩種包裝力價之病毒液;亦提供一系列病毒力價濃縮與定量試劑商品。
細胞不朽化的工具中,SV40 T antigen是最簡單且最常用來造成不朽化細胞生成的方法。多數的病毒基因和抑癌基因(p53、Rb等)的不活化相關,會誘導細胞處於replicative senescence的階段。目前也有研究顯示被感染的細胞,SV40 T anbtigen會誘導端粒酶(Telomerase)的活性。與端粒(telomere)長度相關的Telomerase Reverse Transcriptase protein (TERT)是一種不朽細胞的研究應用。平常細胞中,hTERT是處於不活化態,必要時會進行活化保持telomere的長度,避免細胞發生replicative senescence的現象。某些細胞hTERT 過度表現(over-expression)對於誘發細胞不朽化是無效的(如初代上皮細胞),反而會造成細胞死亡;同時表現hTERT catalytic subunit以及p53或RB siRNA在人類初代卵巢上皮細胞會造成細胞不朽化。過度表現Ras或Myc T58A mutants也有初代細胞不朽化的現象產生。
Decomplement加熱非活化FBS:
1.讓FBS瓶在4°C下完全解凍過夜。
2.將FBS瓶置於56°C的水浴中30分鐘。
Decomplemented FBS可以在-20°C下長期保存。避免頻繁的凍融循環。每2-3天更換一次完整的媒體。不要讓介質顏色變為黃色。
