Zero Blunt™ PCR 克隆如何工作 Zero Blunt™ PCR 克隆试剂盒设计用于在非重组的低背景下克隆平末端 PCR 片段(或任何平末端 DNA 片段)。pCR™-Blunt 载体含有与 LacZα 的 C 端融合的致死性大肠杆菌ccdB 基因(Bernard 等人,1994)。连接平末端 PCR 片段可破坏 lacZα-ccdB 基因融合的表达,从而在转化时仅允许阳性重组体生长。当对转化混合物进行平板接种时,杀死含有非重组载体的细胞。
试剂盒配置 Zero Blunt™ PCR 克隆试剂盒有多种配置可供选择:含 One Shot™ TOPO10 化学感受态大肠杆菌(K2700-20 和 K2700-40)以及不含感受态细胞(K2750-20 和 K2750-40),有 20 次和 40 次反应试剂盒规格。

公式:
length of insert (bp)/length of vector (bp) x ng of vector = ng of insert needed for 1:1 insert:vector ratio
(插入片段长度 (bp) X 载体重量(ng) ) / 载体长度 (bp) = 插入片段:载体比例为1:1时所需的插入片段重量(ng)
Utilization of MHC class I transgenic mice for development of minigene DNA vaccinesencoding multiple HLA-restricted CTL epitopes.
Authors:Ishioka GY, Fikes J, Hermanson G, Livingston B, Crimi C, Qin M, del Guercio MF, Oseroff C, Dahlberg C, Alexander J, Chesnut RW, Sette A
Journal:J Immunol
PubMed ID:10201910
'We engineered a multiepitope DNA minigene encoding nine dominant HLA-A2.1- and A11-restricted epitopes from the polymerase, envelope, and core proteins of hepatitis B virus and HIV, together with the PADRE (pan-DR epitope) universal Th cell epitope and an endoplasmic reticulum-translocating signal sequence. Immunization of HLA transgenic mice with this construct ... More
Interactions between protein kinase CK2 and Pin1. Evidence for phosphorylation-dependent interactions.
Authors: Messenger Moira M; Saulnier Ronald B; Gilchrist Andrew D; Diamond Phaedra; Gorbsky Gary J; Litchfield David W;
Journal:J Biol Chem
PubMed ID:11940573
'The peptidyl-prolyl isomerase Pin1 interacts in a phosphorylation-dependent manner with several proteins involved in cell cycle events. In this study, we demonstrate that Pin1 interacts with protein kinase CK2, an enzyme that generally exists in tetrameric complexes composed of two catalytic CK2 alpha and/or CK2 alpha'' subunits together with two ...

Role of CCAA nucleotide repeats in regulation of hemoglobin and hemoglobin-haptoglobin binding protein genes of haemophilus influenzae.
Authors:Ren Z, Jin H, Whitby PW, Morton DJ, Stull TL
Journal:J Bacteriol
PubMed ID:10482534
'Haemophilus influenzae utilizes hemoglobin and hemoglobin-haptoglobin as heme sources. The H. influenzae hemoglobin- and hemoglobin-haptoglobin binding protein genes, hgpA, hgpB, and hgpC, contain lengths of tetrameric CCAA repeats. Using an hgpA-lacZ translational gene fusion, we demonstrate phase-variable expression of lacZ associated with alteration in the length of the CCAA repeat ... More
Regulation of the Bub2/Bfa1 GAP complex by Cdc5 and cell cycle checkpoints.
Authors: Hu F; Wang Y; Liu D; Li Y; Qin J; Elledge S J;
Journal:Cell
PubMed ID:11733064
'During mitosis, a ras-related GTPase (Tem1) binds GTP and activates a signal transduction pathway to allow mitotic exit. During most of the cell cycle, Tem1 function is antagonized by a GTPase-activating protein complex, Bfa1/Bub2. How the Bfa1/Bub2 complex is regulated is not well understood. We find that Polo/Cdc5 kinase acts ... More
Substantially enhanced cloning efficiency of SAGE (Serial Analysis of Gene Expression) byadding a heating step to the original protocol.
Authors:Kenzelmann M, Muhlemann K
Journal:Nucleic Acids Res
PubMed ID:9889294
'The efficiency of the original SAGE (Serial Analysis of Gene Expression) protocol was limited by a small average size of cloned concatemers. We describe a modification of the technique that overcomes this problem. Ligation of ditags yields concatemers of various sizes. Small concatemers may aggregate and migrate with large ones ... More
