描述

SuperScript® II Reverse Transcriptase (RT) is an improved version of SuperScript® RT. It is a DNA polymerase that synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid. This enzyme is genetically engineered by the introduction of point mutations in the RNase H active center to reduce RNase H activity. This structural modification eliminates degradation of RNA molecules during first-strand cDNA synthesis and gives SuperScript® II RT superior performance characteristics.

• Yield – Reduced RNase H activity results in greater first-strand cDNA yields
• Size of cDNA – Generation of RT-PCR products up to 12 kb
• Thermostability – Full activity at 42°C
• Flexibility – Uses either total or poly(A)+ RNA

Performance and Quality Testing: SDS-PAGE purity; endodeoxyribonuclease, exodeoxyribonuclease, and ribonuclease assays; and yield and length of cDNA product.
Unit Definition: One unit of SuperScript® II is the amount of enzyme required to incorporate 1 nmole of deoxyribonucleotide into acid-precipitable material in 10 min. at 37°C using poly(A)•oligo(dT)12-18 as template•primer (3).
Unit Reaction Conditions: 50 mM Tris-HCl (pH 8.3), 40 mM KCl, 6 mM MgCl2, 1 mM DTT, 0.5 mM [3H]dTTP, 0.1 mM poly(A), 0.1 mM oligo(dT)12-18, 0.1 mg/ml BSA, and enzyme in 50 µl for 10 min. at 37°C.
For Research Use Only. Not intended for any animal or human therapeutic or diagnostic use.

描述

II 型胶原酶是从溶组织梭菌制备,用于细胞和组织的解离。

II 型胶原酶可应用于如下组织制备细胞:


甲状腺
心脏
唾液腺

胶原酶是一种蛋白酶,它能够特异性的结合 Pro-X-Glyc-Pro序列中,中性氨基酸(X)和甘氨酸之间的肽键。该序列高频率的存在于胶原中。胶原酶是唯一的一种可以降解广泛存在于结缔组织中的具有三股螺旋的天然胶原纤维的蛋白酶。

COSMOSIL 5C18-MS-II

仪器简介:

COSMOSIL 5C18-MS-II液相色谱柱采用新的封端技术,可代替COSMOSIL 5C18-MS色谱柱。由于硅胶填料可提取流动相的强极性组分的化学性质,硅胶被极性基体封端可产生屏蔽效应。因此,采用新的封端技术分离碱性化合物时峰形尖锐,硅胶的吸附量小,适合分离螯合化合物。5C18-MS-II另一个优点是与5C18-MS相比保留时间小,5C18-MS-II 更合适于HPLC条件。
