我们所展示的质粒图谱主要是从文献和开放数据库中收集而来，主要是为了方便研究工作，其中一小部分质粒进行了质量控制，可供科学家使用。
所有的产品都严格仅供科学研究使用，不能应用于临床试验，包括人体摄入、注射或外用的药理学用途。
确保质粒的关键元件正确，但是我们并不能保证实验结果。页面展示的图谱序列为理论序列，可能与测序结果不一致，请自行比对后确定是否满足要求。(如果测过序，本页面一般会提供下载)
开放数据库中的大多数载体序列都没有被完全测序。如果实际序列与参考序列的相似度超过99%，则将其视为正确。
由于科学研究是在探索未知，具有很大的不确定性，在任何情况下，我们都不承担超出质粒本身的额外经济损失或责任。

质粒操作方法
1. 发货形式：质粒干粉(常温运输，存于-20度，请务必先转化提质粒后使用)
2. 收到质粒干粉后请先5000rpm离心1min，再加入20μl ddH2O溶解质粒;（质粒复测的浓度有时候与标称值差距较大，这可能是因为冻干质粒在管中的位置、复溶效率、测量偏差以及管壁的吸附导致，因此建议先转化提质粒后再使用）
3. 取1支100μl 感受态于冰上解冻10min，加入2μl质粒，再冰浴30min后，42℃热激60s，不要搅动，再冰浴2min；
4. 加入900μl无抗的LB液体培养基，180rpm震荡37℃培养45min (30℃培养1-1.5小时);
5. 6000rpm离心5min，仅留100μl上清液重悬细菌沉淀，并涂布至目标质粒抗性的LB平板上;
6. 将平板倒置37℃培养14h，如果要求是30℃则培养20h; (菌落过多则将质粒稀释后再转化；没有菌落则加入10μl质粒转化；建议不要直接转表达感受态， 要先转克隆感受态，重提质粒后再导入表达感受态);
7. 挑取单菌落至LB液体培养基中，加入对应抗生素，220rpm震荡培养14h，根据实验需要和质粒提取试剂盒说明书提取质粒。

COMMENT On or before Apr 4, 2002 this sequence version replaced L08654.1,
gi:58257.
The circular sequence is numbered such that 0 is the middle of the
unique EcoRI site and the count increases first through the tet
genes, the pMB1 material, and finally through the Tn3 region.
Plasmid pBR322 contains ampicillin and tetracycline resistance
genes. The ampicillin resistance gene (amp-r) is a penicillin
beta-lactamase. Promoters P1 and P3 are for the beta-lactamase gene.
P3 is the natural promoter, and P1 is artificially created by the
ligation of two different DNA fragments to create pBR322. P2 is in
the same region as P1, but it is on the opposite strand and
initiates transcription in the direction of the tetracycline
resistance gene.
Mutational studies in the primosome assembly sites indicate four
types of mutations: Class I having no effect on the activities
elicited by the DNA site and the bases involved are probably
spacers; Class II requiring higher Mg-2+ concentrations than the
wild-type to be fully activated as factor Y ATPase effectors; Class
III co-inactivating both the ATPase effector and DNA replication
template activity of the site, indicating that they probably
represent essential contact points between factor Y and the DNA;
Class IV having a replication template activity intermediate that of
class III and class II mutant DNAs.
Specific sites within or near the origins of replication are
recognized by dnaA protein. Without dnaA binding to the origin of
replication chromosomal replication is not possible (15). pBR322 DNA
contains two separate regions on opposite strands and close to the
origin of replication which, when in single-stranded form, can act
as effectors for the ATPase activity of E.coli replication factor Y
(5). Small fragments of DNA containing these sites when cloned in
an f1 phage vector act as origins of DNA replication allowing the
formation of complementary double-stranded DNA in
rifampicin-resistant, dna(B,G,C)-dependent fashion in vitro (5). The
biological activity of echinomycin is thought to be related to the
formation of complexes by intercalating with cellular DNA (20).
