Bac-N-Blue™ 线性 DNA 专为与 pBlueBac 载体和 pMelBac 重组而设计。重组病毒具有全长、功能性 lacZ
基因,可产生蓝色斑块。这便于鉴别和纯化。Bac-N-Blue™ DNA 可与基于多角体蛋白启动子的任何杆状病毒转移载体配合使用。Bac-N-Blue™ DNA
在三个位点进行线性化,其中一个位于对病毒增殖至关重要的基因中 (1)。这导致非重组病毒的减少,使得重组病毒的选择和纯化变得简单。除病毒 DNA 外,Bac-N-Blue™ 转染试剂盒还含有 Cellfectin™ 试剂,可实现高转染效率。
仅供科研使用。不可用于诊断程序。

常见问题解答 (FAQ)

白色菌落不能在液体培养基中生长。我该怎么办?

庆大霉素浓度可能过高。尝试降低庆大霉素的浓度至5 µg/mL,并在培养基中加入更多菌落。

为什么会出现蓝色菌落?为什么会出现中心为蓝色而边缘为白色的菌落?

若出现蓝色菌落,则大肠杆菌含有杆粒和质粒,使细胞能在筛选过程中存活。但是,由于未发生转座,所以LacZ基因未被破坏。靶心菌落表示在菌落生长时发生转座。将从混合克隆白色部分中分离得到的克隆重新划线,应该能够得到发生过转座的菌落。

我得到的主要是白色/野生型空斑,而不是蓝色/重组型空斑。哪里出错了?

这是同源性重组较差的典型标志。应检查使用的质粒/线性DNA比例。但是,如果存在一些蓝色空斑,则对那些病毒进行扩增并检测它们的蛋白。根据我们的经验,它们应该是正确的,即使其丰度相对较低。

感染细胞后,我在一个细胞中看到较大的多角体,而在相邻细胞中看到较小的多角体(数量更多)。这正常吗?

是的,细胞被单个野生型病毒感染后,会以不同速度生成多角体,直到培养瓶中所有的细胞都被感染。细胞中多角体的形成需要3-4天左右,其大小和数量各不相同,直至达到最大能力并发生细胞破裂,从而将微小的病毒颗粒释放到培养基中。

我担心得不到空斑。出现空斑需要几天?空斑通常为多大?

正常情况下,约5-7天会出现很小的白点,约10天出现1 mm空斑。空斑的大小范围为1 mm至4 mm。

OX40 stimulation by gp34/OX40 ligand enhances productive human immunodeficiency virus type 1 infection.
Authors: Takahashi Y; Tanaka Y; Yamashita A; Koyanagi Y; Nakamura M; Yamamoto N;
Journal:J Virol
PubMed ID:11435553
'OX40 is a member of the tumor necrosis factor (TNF) receptor superfamily and known to be an important costimulatory molecule expressed on activated T cells. To investigate the role of costimulation of OX40 in human immunodeficiency virus type 1 (HIV-1) infection by its natural ligand, gp34, the OX40-transfected ACH-2 cell ... More
Identification of the major synaptojanin-binding proteins in brain.

Journal:J Biol Chem
PubMed ID:9079704
'Synaptojanin is a nerve-terminal enriched inositol 5-phosphatase thought to function in synaptic vesicle endocytosis, in part through interactions with the Src homology 3 domain of amphiphysin. We have used synaptojanin purified from Sf9 cells after baculovirus mediated expression in overlay assays to identify two major synaptojanin-binding proteins in rat brain. ... More
Identification of a novel human eicosanoid receptor coupled to G(i/o).

'We have conducted an in silico data base search for and cloned a novel G-protein-coupled receptor (GPCR) named TG1019. Dot and Northern blotting analyses showed that transcripts of the novel GPCR were expressed in various tissues except brain, and the expression was more intense in liver, kidney, peripheral leukocyte, lung, ... More
VRILLE feeds back to control circadian transcription of Clock in the Drosophila circadian oscillator.
Authors:Glossop NR, Houl JH, Zheng H, Ng FS, Dudek SM, Hardin PE,
Journal:Neuron
PubMed ID:12546820
'The Drosophila circadian oscillator consists of interlocked period (per)/timeless (tim) and Clock (Clk) transcriptional/translational feedback loops. Within these feedback loops, CLK and CYCLE (CYC) activate per and tim transcription at the same time as they repress Clk transcription, thus controlling the opposite cycling phases of these transcripts. CLK-CYC directly bind ... More
Accurate processing and secretion in the baculovirus expression system of an erythroid-cell-stimulating factor consisting of a chimaera of insulin-like growth factor II and an insect insulin-like peptide.
Authors:Congote LF, Li Q

'A synthetic gene encoding the signal peptide and the N-terminal sequence of bombyxin, an insect insulin-like peptide, and the 58 amino acids of the C-terminal sequence of human insulin-like growth factor II (IGF II) has been expressed using the baculovirus system.
