人肺癌细胞；A549 [A-549]图片在培养瓶长成致密单层后，已基本上饱和，为使细胞能继续生长，同时
也将细胞数量扩大，就必须进行传代(再培养)。 传代培养也是一种将细胞种保存下去的方法。同时也是利用培养细胞进行各种实验的必经过程。悬浮型细胞直接分瓶就可以，而贴壁细胞需经消化后才能分瓶。
冷冻保存方法一：冷冻管置于4℃300分钟→(-20℃30分钟*)→-80℃16~18小时(或隔夜)→液氮槽*储存。
冷冻保存方法二：冷冻管置于已设定程序之可程序降温机中每分钟降1-3℃至–80℃以下，再放入液氮槽期储存。-20℃不可超过1小时，以防止冰晶过大，造成细胞大量死亡，也可跳过此步骤直接放入-80℃冰箱中，但存活率稍微降低一些。
迄今为止，公司收录背景资料清晰，细胞活力状态良好的细胞株1420株，其中绝大部分是近年来从美国ATCC和NIH分批引进的细胞种子，少部分来自全国各地细胞研究所，细胞来源可靠，背景资料清晰，代数年轻，活力好
传代方法：细胞*汇合时，倒掉旧液，加入消化液（0.25%*+0.03%EDTA）2ml消化，显微镜下观察细胞*脱离瓶壁分离成单个细胞后弃掉*，加培养基混匀分瓶，T25瓶中加培养基至6-8ml，T75瓶加培养基至20ml，37℃，5%CO2孵箱培养。
培养是生物学和医学研究zui常用的手段之一，可分为原代培养和传代培养两种。原代培养是直接从生物体获取细胞进行培养。由于细胞刚刚从活体组织分离出来，故更接近于生物体内的生活状态。这一方法可为研究生物体细胞的生长、代谢、繁殖提供有力的手段，同时也为以后传代培养创造条件。利用此方法还可直接服务于临床实践
操作步骤：
1）贴壁细胞传代：提前将培养基、PBS放入37℃水浴锅内预热，用75%酒精擦拭后再放入超净台内，吸除或倒掉细胞瓶内旧培养液，加少量PBS润洗细胞，加入适量*，使*的量能盖住细胞，37℃孵育，每隔2~3min显微镜下观察，待贴壁细胞间间隙变大、细胞趋于圆形但还未漂起时弃去*，加入新鲜培养基，晃动细胞瓶，终止*作用，用吸管小心吹打贴壁的细胞，制成细胞悬液。控制吹打的力度，避免产生大量的气泡，将细胞悬液分别接种到另外的2~3个细胞瓶内，加入新鲜培养基，置37℃温箱培养，隔天观察贴壁生长情况。
2）悬浮细胞传代：将细胞悬液转移到无菌离心管内，1000rpm离心5min，弃去上清，加入新鲜的培养基，用吸管小心吹散沉淀，制成细胞悬液，将细胞悬液分别接种到另外的2~3个细胞瓶内，加入新鲜培养基，置37℃温箱培养。

产品介绍 This gene encodes a small glycolipid transport protein which acts as a substrate specific co-factor for the lysosomal enzyme beta-hexosaminidase A. Beta-hexosaminidase A, together with GM2 ganglioside activator, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Mutations in this gene result in GM2-gangliosidosis type AB or the AB variant of Tay-Sachs disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2009].
Function : Binds gangliosides and stimulates ganglioside GM2 degradation. It stimulates only the breakdown of ganglioside GM2 and glycolipid GA2 by beta-hexosaminidase A. It extracts single GM2 molecules from membranes and presents them in soluble form to beta-hexosaminidase A for cleavage of N-acetyl-D-galactosamine and conversion to GM3.
Subcellular Location : Lysosome.
Post-translational modifications : The serines in positions 32 and 33 are absent in 80% of the sequenced protein.
DISEASE : Defects in GM2A are the cause of GM2-gangliosidosis type AB (GM2GAB) [MIM:272750]; also known as Tay-Sachs disease AB variant. GM2-gangliosidosis is an autosomal recessive lysosomal storage disease marked by the accumulation of GM2 gangliosides in the neuronal cells. GM2GAB is characterized by GM2 gangliosides accumulation in the presence of both hexosaminidase A and B.

产品介绍 GMEB-1 is a 573 amino acid protein that contains one SAND domain and is a member of the KDWK family of combinatorial transcription modulators. Localized to both the cytoplasm and the nucleus, GMEB-1 forms a heterodimer with GMEB-2 (Glucocorticoid modulatory element-binding protein 2) and, once associated with GMEB-2, plays a key role in parvovirus DNA replication. In addition, GMEB-1 functions alone as a trans-acting factor that, by binding to glucocorticoid modulatory elements (GMEs) in TAT (tyrosine aminotransferase) promoters, increases intracellular sensitivity to glucocorticoid concentrations. GMEB-1 also interacts with initiator procaspases and, via this interaction, can inhibit caspase-induced apoptosis. Due to alternative splicing events, GMEB-1 is expressed as two isoforms.
Function : Trans-acting factor that binds to glucocorticoid modulatory elements (GME) present in the TAT (tyrosine aminotransferase) promoter and increases sensitivity to low concentrations of glucocorticoids. Binds also to the transferrin receptor promoter. Essential auxiliary factor for the replication of parvoviruses.
Subunit : Homodimer, and heterodimer of GMEB1 and GMEB2. GMEB1 and GMEB2 form the parvovirus initiator complex (PIF). Interacts with the glucocorticoid receptor (NR3C1) and NCOA2/TIF2 (By similarity). May interact with HSP27 and CREB-binding protein (CBP).
Subcellular Location : Nucleus. Cytoplasm. May be also cytoplasmic.
Similarity : Contains 1 SAND domain.
