品Pai:百奥莱博
产地:国产|进口
SSC缓冲溶液是分子生物学中Z标准的印迹和杂交处理溶液,旨在用于各种杂交实验达到变性和清洗的目的,主要成分为*化*和柠檬酸*。SSC缓冲液中柠檬酸*起缓冲作用,盐离子(Na )中和核酸主链上的负电荷,使其呈电中性,这样可以使探针和靶序列的结合比较容易进行。也用于SDS-PAGE电泳分离胶配制。用于核酸杂交,不同浓度作用不同:常用2×,及0.5×
2×SSC:高盐洗膜,洗去部分非特异性结合的探针。
0.5×SSC:低盐洗膜,增加核酸链的严紧性,使得 RNA/DNA 之间的排斥力增加。
本产品为20×浓缩液,经过滤高压CJ处理,可根据实验要求使用去离子水直接稀释使用。
储存条件:常温

产品说明:
Mitomycin C is produced by a strain of actinomyces named Streptomyces caespitosus. The structural formula of Mitomycin C is a combination of three of the representative anticancerous radicals, quinone, urethane and aziridine group. It is supplied in a vial containing 2 mg Mitomycin C,The other In-active ingredient in Mitomycin-C is Sodium Chloride.
Mitomycin C is widely used among the Mitomycin group of antibiotics because it is the least toxic and with the most potent antitumor activity. It has extraordinarily strong activity against Ehrlich ascites tumor cell.It also possesses strong bactericidal action against gram-positive and gram-negative organisms.
Mitomycin C inhibits DNA synthesis. It reacts covalently with DNA, in vivo and in vitro, forming cross-links between the complementary strands of DNA. This interaction prevents the separation of the complementary DNA strand, thus inhibiting DNA replication. Mitomycin C is one of the few antibiotics known to interact with DNA in this fashion.
The recommended concentration for eukaryote cell culture use is 10-50 µg/mL.
Preparation Instructions
Mitomycin C is soluble in water.The solubility at 0.5 mg/mL (1 vial/4 mL) in water yields a clear blue solution. The contents of one vial dissolved in 4 mL water produces a solution that is 1.5mM Mitomycin C. A 0.5% solution in water has a pH of 6.0-7.5.A saturated solution has a pH of 5.0-9.0.
Mitomycin C undergoes rapid degradation in acidic solutions (pH less than 6.0). It is most stable in aqueous solutions at pH 6-9. Generally, solutions at pH 6-9 can be stored at 0-5℃ for up to a week. If a precipitate forms, a fresh solution should be prepared. The precipitated solution has proven to be toxic to cells. Stock solutions should also be stored in the dark since it is readily decomposed by light.
A study has shown that the amount of Mitomycin C in a culture medium (at 38℃) containing antibiotics with fetal calf serum was reduced by 29% after 30 minutes and by 53% after 60 minutes.
