細(xì)胞名稱:人卵巢畸胎瘤細(xì)胞;PA-1培養(yǎng)
細(xì)胞形態(tài): 細(xì)胞株
生長(zhǎng)特性:貼壁 懸浮 半貼壁
傳代時(shí)間:2-3天 3-5天
傳代比例:1:2~1:3 1:1~1:2

細(xì)胞在培養(yǎng)瓶長(zhǎng)成致密單層后,已基本上飽和,為使細(xì)胞能繼續(xù)生長(zhǎng),同時(shí)
也將細(xì)胞數(shù)量擴(kuò)大,就必須進(jìn)行傳代(再培養(yǎng))。 傳代培養(yǎng)也是一種將細(xì)胞種保存下去的方法。同時(shí)也是利用培養(yǎng)細(xì)胞進(jìn)行各種實(shí)驗(yàn)的必經(jīng)過(guò)程。懸浮型細(xì)胞直接分瓶就可以,而貼壁細(xì)胞需經(jīng)消化后才能分瓶。
人卵巢畸胎瘤細(xì)胞;PA-1培養(yǎng)細(xì)胞培養(yǎng)
1、冷凍管應(yīng)如何解凍?
取出冷凍管后, 須立即放入37 ℃水槽中快速解凍, 輕搖冷凍管使其在1 分鐘內(nèi)全部融化, 并注意水面不可超過(guò)冷凍管蓋沿, 否則易發(fā)生污染情形。另冷凍管由液氮桶中取出解凍時(shí), 必須注意安全, 預(yù)防人卵巢畸胎瘤細(xì)胞;PA-1培養(yǎng)冷凍管之爆裂。
2、細(xì)胞冷凍管解凍培養(yǎng)時(shí), 是否應(yīng)馬上去除DMSO?
除少數(shù)特別注明對(duì)DMSO 敏感之細(xì)胞外, 絕大部分細(xì)胞株(包括懸浮性細(xì)胞), 在解凍之后, 應(yīng)直接放入含有10-15ml新鮮培養(yǎng)基之培養(yǎng)角瓶中, 待隔天再置換新鮮培養(yǎng)基以去除DMSO 即可, 如此可避免大部分解凍后細(xì)胞無(wú)法生長(zhǎng)或貼附之問(wèn)題。
3、可否使用與原先培養(yǎng)條件不同之培養(yǎng)基?
不能。每一細(xì)胞株均有其特定使用且已適應(yīng)之細(xì)胞培養(yǎng)基, 若驟然使用和原先提供之培養(yǎng)條件不同之培養(yǎng)基, 細(xì)胞大都無(wú)法立即適應(yīng), 造成細(xì)胞無(wú)法存活。
4、可否使用與原先培養(yǎng)條件不同之血清種類?
不能。血清是細(xì)胞培養(yǎng)上一個(gè)極為重要的營(yíng)養(yǎng)來(lái)源, 所以血清的種類和品質(zhì)對(duì)于細(xì)胞的生長(zhǎng)會(huì)產(chǎn)生*的影響。來(lái)自不同物種的血清, 在一些物質(zhì)或分子的量或內(nèi)容物上都有所不同,血清使用錯(cuò)誤常會(huì)造成細(xì)胞無(wú)法存活。

產(chǎn)品介紹 GNL2 is a nucleolar guanasine-triphosphate binding protein that is ubiquitously expressed at low levels in almost all tissues. GNL2 is involved in the crucial process of trafficking proteins out of the nucleus. Specifically, it is a GTPase that interacts with the 60s preribosomal subunit in the nucleus and facilitates export of the subunit into the cytoplasm. GTPases are responsible for the hydrolysis of GTP by way of a protein region dubbed the G domain. GTPases are often involved in the translocating proteins through membranes gleaning energy for the activity by hydrolizing GTP. GNL2 shares G domain homology and some functionality with nucleostemin (GNL3), another nuclear GTPase. Highest expression of GNL2 is found in testis.
Function : GTPase that associates with pre-60S ribosomal subunits in the nucleolus and is required for their nuclear export and maturation.
Subcellular Location : Nucleus; nucleolus.
Tissue Specificity : Ubiquitously expressed at relatively low levels in all human tissues tested, with the highest level of expression in the testes.
Similarity : Belongs to the MMR1/HSR1 GTP-binding protein family. NOG2 subfamily.
Contains 1 G (guanine nucleotide-binding) domain.
Database links : UniProtKB/Swiss-Prot: Q13823.1

產(chǎn)品介紹 GTPases from the MMR1/HSR1 GTP-binding protein subfamily are circularly rearranged G-motifs that play a critical role in maintaining normal cell growth. Deletion of these genes results in severe growth defects with a marked reduction in mature rRNA species and a concomitant accumulation of the 35S pre-rRNA transcript. Deletion also causes the ribosomal protein Rpl25a to fail exportation from the nucleolus. Deletion of any of the G-domain motifs will result in a null phenotype and nuclear/nucleolar localization that lacks the nucleolar export of preribosomes and is accompanied by a distortion of the nucleolar structure. GNL3L (guanine nucleotide binding protein-like 3 (nucleolar)-like) is a 582 amino acid nuclear protein that belongs to the MMR1/HSR1 GTP-binding protein family. Containing one G (guanine nucleotide-binding) domain, GNL3L is required for normal processing of ribosomal pre-rRNA and for cell proliferation.
Function : Stabilizes TERF1 omeric association by preventing TERF1 recruitment by PML. Stabilizes TERF1 protein by preventing its ubiquitination and hence proteasomal degradation. Does so by interfering with TERF1-binding to FBXO4 E3 ubiquitin-protein ligase. Required for cell proliferation. By stabilizing TRF1 protein during mitosis, promotes metaphase-to-anaphase transition. Stabilizes MDM2 protein by preventing its ubiquitination, and hence proteasomal degradation. By acting on MDM2, may affect TP53 activity. Required for normal processing of ribosomal pre-rRNA. Binds GTP.
Subunit : Interacts with MDM2; this interaction, which occurs in the nucleoplasm, stabilizes MDM2. Indirectly interacts with TP53, via MDM2-binding. Interacts with TERF1; this interaction probably occurs in the nucleoplasm and is increased during mitosis, when the nucleolus is disassembled. This binding may promote TERF1 homodimerization. Interacts with TERT.
Subcellular Location : Nucleus, nucleolus.
Similarity : Belongs to the MMR1/HSR1 GTP-binding protein family.
Contains 1 G (guanine nucleotide-binding) domain.
