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。

Abstract
Cytoskeletal changes regulated by the PAK4 serine/threonine kinase are mediated by LIM kinase 1 and cofilin.
Authors: Dan C; Kelly A; Bernard O; Minden A;
Journal:J Biol Chem
PubMed ID:11413130
'PAK4 is the most recently identified member of the PAK family of serine/threonine kinases. PAK4 differs from other members of the PAK family in sequence and in many of its functions. Previously, we have shown that an important function of this kinase is to mediate the induction of filopodia in ... More
Sp3 Represses Gene Expression via the Titration of Promoter-specific Transcription Factors.
Authors: Kennett Sarah B; Moorefield K Scott; Horowitz Jonathan M;
Journal:J Biol Chem
PubMed ID:11773047
'We have determined previously that Sp3 encodes three distinct gene products as follows: a full-length protein (Sp3) that is an activator of transcription and two isoforms (M1 and M2) derived via internal translational initiation that function as transcriptional repressors. To identify amino acids and functions required for transcriptional repression, we ... More
Identification of phosphorylated residues that affect the activity of the mitotic kinase Aurora-A.
Authors: Littlepage Laurie E; Wu Hua; Andresson Thorkell; Deanehan Julia K; Amundadottir Laufey T; Ruderman Joan V;
Journal:Proc Natl Acad Sci U S A
PubMed ID:12422018
'The activity of the kinase Aurora-A (Aur-A) peaks during mitosis and depends on phosphorylation by one or more unknown kinases. Mitotic phosphorylation sites were mapped by mass spec sequencing of recombinant Aur-A protein that had been activated by incubation in extracts of metaphase-arrested Xenopus eggs. Three sites were identified: serine ... More
15-Lipoxygenase metabolism of 2-arachidonylglycerol. Generation of a peroxisome proliferator-activated receptor alpha agonist.

Journal:J Biol Chem
PubMed ID:11956198
'The recent demonstrations that cyclooxygenase-2 and leukocyte-type 12-lipoxygenase (LOX) efficiently oxygenate 2-arachidonylglycerol (2-AG) prompted an investigation into related oxygenases capable of metabolizing this endogenous cannabinoid receptor ligand. We evaluated the ability of six LOXs to catalyze the hydroperoxidation of 2-AG. Soybean 15-LOX, rabbit reticulocyte 15-LOX, human 15-LOX-1, and human 15-LOX-2 ... More
Recombinant Dicer efficiently converts large dsRNAs into siRNAs suitable for gene silencing.
Authors:Myers JW, Jones JT, Meyer T, Ferrell JE,
Journal:Nat Biotechnol
PubMed ID:12592410
RNA interference (RNAi) is a powerful method for specifically silencing gene expression in diverse cell types. RNAi is mediated by approximately 21-nucleotide small interfering RNAs (siRNAs), which are produced from larger double-stranded RNAs (dsRNAs) in vivo through the action of Dicer, an RNase III-family enzyme. Transfecting cells with siRNAs rather ... More
