质粒图谱查询方法

3.google scholar: / 有些质粒是经过改造的,所以通过上述方法不能查询到相应信息。这时,可以在google scholar中输入质粒名称,可以直观地看哪些学者在何文章中使用了该质粒,从而可了解到质粒的来源;或者籍此向作者咨询或索取。 4.尝试从各大生物公司,例如invitrogen网站查询. 5. 这个网站收录了大量图谱: http://www.embl-hamburg.de/~geerlof/webPP/vectordb/bact_vectors/table.html

pEGFP-C1质粒图谱介绍

(PR29971; published 03 October 2002)Restriction Map and Multiple Cloning Site (MCS) of pEGFP-C1. All restriction sites shown are unique. The Xba I and Bcl I sites (*) are methylated in the DNA provided by BD Biosciences Clontech. If you wish to digest the vector with these enzymes, you will need to transform the vector into a dam – host and make fresh DNA.DescriptionpEGFP-C1 encodes a red-shifted variant of wild-type GFP (1–3) which has been optimized for brighter fluorescence and higher expression in mammalian cells. (Excitation maximum = 488 nm;emission maximum = 507 nm.) pEGFP-C1 encodes the GFPmut1 variant (4) which contains the double-amino-acid substitution of Phe-64 to Leu and Ser-65 to Thr. The coding sequence of the EGFP gene contains more than 190 silent base changes which correspond to human codon-usage preferences (5). Sequences flanking EGFP have been converted to a Kozak consensus translation initiation site (6) to further increase the translation efficiency in eukaryotic cells. The MCS in pEGFP-C1 is between the EGFP coding sequences and the SV40 poly A. Genes cloned into the MCS will be expressed as fusions to the C-terminus of EGFP if they are in the same reading frame as EGFP and there are no intervening stop codons. SV40 polyadenylation signals downstream of the EGFP gene direct proper processing of the 3' end of the EGFP mRNA. The vector backbone also contains an SV40 origin for replication in mammalian cells expressing the SV40 T-antigen. A neomycin resistance cassette (Neo r ), consisting of the SV40 early promoter, the neomycin/kanamycin resistance gene of Tn5, and polyadenylation signals from the Herpes simplex virus thymidine kinase (HSV TK) gene, allows stably transfected eukaryotic cells to be selected using G418. A bacterial promoter upstream of this cassette expresses kanamycin resistance in E. coli . The pEGFP-C1backbone also provides a pUC origin of replication for propagation in E. coli and an f1 origin for single-stranded DNA production.pEGFP-C1 Vector Information PT3028-5GenBank Accession #: U55763Catalog #6084-1(1642)(2577)Ase I(597) I (601)Eco (3854)G I (1323)TCC GGA CTC AGA TCT CGA GCT CAA GCT TCG AAT TCT GCA GTC GAC GGT ACC GCG GGC CCG GGA TCC ACC GGA TCT AGA TAA CTG ATC AHin d III Xho I Apa I Bsp 120 I Kpn I Asp 718 I Bam H I Xba I* Xma I Sma ISac II Sal I Acc I Sac I Ecl 136 II Eco R I Pst I Bsp E I Bgl II Bcl I*UseFusions to the C terminus of EGFP retain the fluorescent properties of the native protein allowing the localization of the fusion protein in vivo. The target gene should be cloned into pEGFP-C1 so that it is in frame with the EGFP coding sequences, with no intervening in-frame stop codons. The recombinant EGFP vector can be transfected into mammalian cells using any standard transfection method. If required, stable transformants can be selected using G418 (7). pEGFP-C1 can also be used simply to express EGFP in a cell line of interest (e.g., as a transfection marker).
