TA 克隆™试剂盒(含 PCR™2.1 载体)提供了一种快速的一步法克隆策略,可将经 Taq 扩增的 PCR 产物直接插入质粒载体中。TA Cloning™ 试剂盒使用 pCR™2.1 克隆载体和 ExpressLink™ T4 DNA 连接酶,在十五分钟的室温连接步骤中生成连接产物。反应通常产生 >80% 包含插入片段的重组体。

TA Cloning™ 试剂盒(含 pCR™2.1 载体)的特点:
快速且方便 — 15分钟、室温连接
高效 — 蓝/白斑筛选和 >80% 含正确插入片段的克隆体
灵活 — 可选择卡那霉素或氨苄青霉素抗性,实现灵活的抗生素选择
轻松 — 无需对 PCR 产物进行任何酶修饰
流程简化 — 不需要使用包含限制性位点的 PCR 引物

pCR™2.1 载体提供:
• 3'-T 突出端,用于直接连接 Taq 扩增 PCR 产物
• T7 启动子,用于体外 RNA 转录和测序
• 两侧具有 EcoR I 位点的通用性多位点接头,可方便地切除插入片段
• M13 正向和反向引物位点,用于测序

TA Cloning™ 的工作原理
Taq 聚合酶具有非模板依赖性活性,可在 PCR 产物的 3' 末端引入单脱氧腺苷 (A)。该试剂盒中提供的线性化载体具有单个 3' 脱氧胸苷 (T) 残基。这使得 PCR 插入片段高效地与载体连接。

试剂盒配置
TA Cloning™ 试剂盒提供多种配置:不含感受态细胞(K2020-20 和 K2020-40)、含 One Shot™ INVF' 化学感受态大肠杆菌(K2000-01 和 K2000-40)、含 One Shot™ TOP10F' 化学感受态大肠杆菌(K2030-01 和 K2030-40)以及含 One Shot™ TOP10 化学感受态大肠杆菌(K2040-01 和 K2040-40),分 20 和 40 次反应试剂盒规格。

Abstract
Differential gene expression between developing queens and workers in the honey bee, Apis mellifera [see comments]
Authors:Evans JD, Wheeler DE
Journal:Proc Natl Acad Sci U S A
PubMed ID:10318926
'Many insects show polyphenisms, or alternative morphologies, which are based on differential gene expression rather than genetic polymorphism. Queens and workers are alternative forms of the adult female honey bee and represent one of the best known examples of insect polyphenism. Hormonal regulation of caste determination in honey bees has ... More
An imprinted, mammalian bicistronic transcript encodes two independent proteins.
Authors:Gray TA, Saitoh S, Nicholls RD
Journal:Proc Natl Acad Sci U S A
PubMed ID:10318933
Polycistronic transcripts are common in prokaryotes but rare in eukaryotes. Phylogenetic analysis of the SNRPN (SmN) mRNA in five eutherian mammals reveals a second highly conserved coding sequence, termed SNURF (SNRPN upstream reading frame). The vast majority of nucleotide substitutions in SNURF occur in the wobble codon position, providing strong ... More
PCR-mediated recombination: a general method applied to construct chimeric infectious molecular clones of plasma-derived HIV-1 RNA.
Authors:Fang G, Weiser B, Visosky A, Moran T, Burger H
Journal:Nature Medicine
PubMed ID:9930876
A PCR-based approach was developed that provides a powerful tool for engineering recombinant molecules without reliance on restriction sites. DNA sequences were first amplified by high-fidelity PCR using Pfu polymerase; they were then used both as 'megaprimers' and templates in subsequent asymmetric long PCR amplifications to form chimeric clones. To ... More
Sequence evolution and copy number of Ty1-copia retrotransposons in diverse plant genomes.
Authors: Navarro-Quezada Aura; Schoen Daniel J;
Journal:Proc Natl Acad Sci U S A
PubMed ID:11752395
Sequence evolution of the reverse transcriptase (RT) gene in retrotransposons belonging to the Ty1-copia class was studied in 11 plant species. Phylogenetic reconstruction of the evolutionary history of RT sequences indicated a strong pattern of purifying selection, manifested as high ratios of third to first plus second codon position substitutions, ... More
Immunogene therapy of tumors with vaccine based on Xenopus homologous vascular endothelial growth factor as a model antigen.

Journal:Proc Natl Acad Sci U S A
PubMed ID:11553767
Overcoming immune tolerance of the growth factors associated with tumor growth should be a useful approach to cancer therapy by active immunity. We used vascular endothelial growth factor (VEGF) as a model antigen to explore the feasibility of the immunogene tumor therapy with a vaccine based on a single xenogeneic ... More
