纯化的抗体可通过不同的途径获取,有些DNA复制抑制因子抗体可通过下述方法制备或从商家购买。从商家购买的抗体,通常附有正确的储存方法。
1)工作液应在4℃下融化并存放,可能稳定达数月。
2)如果没有特殊原因而避免使用叠氮钠,亦可加入叠氮钠,浓度为0.02%。将纯化的抗体样本分装成合适的体积,于-20℃保存。
3)纯化的抗体溶液应以较高的浓度(如lmg/m1)在中性pH下保存。:常用的抗体储存浓度高达l0mg/ml。较低浓度的抗体冻存前应浓缩。所有标准的浓缩方法(如超滤法),皆可使用。还有一个简单的方法是用蛋白A或蛋白G亲和柱来浓缩溶液。如果纯化的抗体不是用于标记,可将它们以较低浓度储存于加有1%BSA的溶液中。
4)经纯化制备的抗体在常用的缓冲液中是稳定的。其DH应保持在中性左右。如果pH在7-8之间,即使保存多年,对抗体也无损害。多数情况下,盐浓度适于保持在0-150mmol/L之间,但在长期存放的抗体中,盐溶液浓度高达500mmol/L时,对DNA复制抑制因子抗体能有损害。如果没有其他说明.律议用PBS或50mmol/LTris(DH8.0)溶液长期存放抗体。

DNA复制抑制因子抗体产品介绍 Inhibits DNA replication by preventing the incorporation of MCM complex into prereplication complex (pre-RC). It is degraded during the mitotic phase of the cell cycle. Its destruction at the metaphase-anaphase transition permits replication in the succeeding cell cycle.
Geminin is a nuclear protein that regulates the initiation of DNA replication during the cell cycle. DNA replication requires the coordinated association of cdc6 and minichromosome maintenance (MCM) proteins with chromatin. Geminin blocks this assembly of the MCM into the prereplication complex and, in turn, prevents replication from occurring. Expression of geminin fluctuates throughout the cell cycle with geminin levels lowest at G1. Throughout S, G2 and M phases, geminin levels are consistently elevated followed by a decrease during mitosis. The initiation of DNA replication is dependent on the the degradation of geminin during mitosis and the absence of geminin throughout G1 phase. Geminin degradation is mediated by the anaphase-promoting complex (APC), which specifically targets B-type cyclins and other proteins containing a destruction box motif for degradation by ubiquitin-mediated proteolysis.
Subunit : Homotetramer. Interacts with CDT1; inhibits binding of the MCM complex to origins of replication. Interacts with IDAS; targets GMNN to the nucleus, prevents GMNN interaction with CDT1 and competes with IDAS homodimerization.
Subcellular Location : Cytoplasm. Nucleus. Note=Mainly cytoplasmic but can be relocalized to the nucleus.
Similarity : Belongs to the geminin family.
