人肺癌細胞；A549 [A-549]圖片在培養瓶長成致密單層后，已基本上飽和，為使細胞能繼續生長，同時
也將細胞數量擴大，就必須進行傳代(再培養)。 傳代培養也是一種將細胞種保存下去的方法。同時也是利用培養細胞進行各種實驗的必經過程。懸浮型細胞直接分瓶就可以，而貼壁細胞需經消化后才能分瓶。
冷凍保存方法一：冷凍管置于4℃300分鐘→(-20℃30分鐘*)→-80℃16~18小時(或隔夜)→液氮槽*儲存。
冷凍保存方法二：冷凍管置于已設定程序之可程序降溫機中每分鐘降1-3℃至–80℃以下，再放入液氮槽期儲存。-20℃不可超過1小時，以防止冰晶過大，造成細胞大量死亡，也可跳過此步驟直接放入-80℃冰箱中，但存活率稍微降低一些。
迄今為止，公司收錄背景資料清晰，細胞活力狀態良好的細胞株1420株，其中絕大部分是近年來從美國ATCC和NIH分批引進的細胞種子，少部分來自全國各地細胞研究所，細胞來源可靠，背景資料清晰，代數年輕，活力好
傳代方法：細胞*匯合時，倒掉舊液，加入消化液（0.25%*+0.03%EDTA）2ml消化，顯微鏡下觀察細胞*脫離瓶壁分離成單個細胞后棄掉*，加培養基混勻分瓶，T25瓶中加培養基至6-8ml，T75瓶加培養基至20ml，37℃，5%CO2孵箱培養。
培養是生物學和醫學研究zui常用的手段之一，可分為原代培養和傳代培養兩種。原代培養是直接從生物體獲取細胞進行培養。由于細胞剛剛從活體組織分離出來，故更接近于生物體內的生活狀態。這一方法可為研究生物體細胞的生長、代謝、繁殖提供有力的手段，同時也為以后傳代培養創造條件。利用此方法還可直接服務于臨床實踐
操作步驟：
1）貼壁細胞傳代：提前將培養基、PBS放入37℃水浴鍋內預熱，用75%酒精擦拭后再放入超凈臺內，吸除或倒掉細胞瓶內舊培養液，加少量PBS潤洗細胞，加入適量*，使*的量能蓋住細胞，37℃孵育，每隔2~3min顯微鏡下觀察，待貼壁細胞間間隙變大、細胞趨于圓形但還未漂起時棄去*，加入新鮮培養基，晃動細胞瓶，終止*作用，用吸管小心吹打貼壁的細胞，制成細胞懸液。控制吹打的力度，避免產生大量的氣泡，將細胞懸液分別接種到另外的2~3個細胞瓶內，加入新鮮培養基，置37℃溫箱培養，隔天觀察貼壁生長情況。
2）懸浮細胞傳代：將細胞懸液轉移到無菌離心管內，1000rpm離心5min，棄去上清，加入新鮮的培養基，用吸管小心吹散沉淀，制成細胞懸液，將細胞懸液分別接種到另外的2~3個細胞瓶內，加入新鮮培養基，置37℃溫箱培養。

產品介紹 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.

產品介紹 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.
