What is a pBluescript?
The pBluescript II phagemids (plasmids with a phage origin) are cloning vectors designed to simplify commonly used cloning and sequencing procedures, including the construction of nested deletions for DNA sequencing, generation of RNA transcripts in vitro and site-specific mutagenesis and gene mapping.
What is lambda ZAP?
Lambda ZAP: a bacteriophage lambda expression vector with in vivo excision properties.
What is the function of phagemid?
A phagemid (plasmid + phage) is a plasmid that contains an f1 origin of replication from an f1 phage. It can be used as a type of cloning vector in combination with filamentous phage M13. A phagemid can be replicated as a plasmid, and also be packaged as single stranded DNA in viral particles.
Why is pBluescript useful?
pBluescriptII: Multifunctional Cloning and Mapping Vectors The versatility of pBluescript vectors alleviates the need for successive subcloning. With 21 restriction sites, in two orientations, most cloned genes can be inserted directionally into the pBluescript polylinkers.
What is the size of pBluescript?
Plasmid: pBluescript SK (+)
| Source/Vendor: | Stratagene |
|---|---|
| Plasmid Type: | Bacterial Expression |
| Cloning Method: | Restriction Enzyme |
| Size: | 2958 |
| 5′ Sequencing 1 Primer: | M13pUC-fwd |
What is lambda ZAP II?
The Lambda ZAP II vectors combine the high efficiency of lambda vector systems with the versatility of plasmid systems. They enable prokaryotic expression of your gene of interest under control of the lac promoter.
How can lambda ZAP 2 Recombinant be distinguished?
2. How can lambda-ZAPII recombinants be distinguished? Explanation: Insertion of foreign DNA in the polylinker containing restriction sites leads to inactivation of the lacZ’ gene. Hence recombinants can be distinguished as white colonies from non-Recombinant blue colonies.
Is pBluescript a phagemid?
The pBluescript vectors, e.g., pBluescript II KS/SK(+ / –) (3 kb), are phagemids derived from pUC19 and have essentially similar configurations as pGEM-Zf except that they have T7 and T3 promoters, respectively, flanking the MCS which is composed of 21 unique restriction sites (95).
How do you choose the best vector?
Choosing the right plasmid vector: A Guide for beginners
- Insert Size: large or small? The only aspect to consider here is whether you’re cloning a large or small DNA fragment.
- Copy Number: high or low?
- Cloning Sites: which restriction enzymes?
- Antibiotic resistance: why is it needed?
- A few criteria to avoid a headache!
What is pBluescript II?
Agilent pBlueScript II Vectors are powerful cloning vectors for a range of research applications. Featuring an extensive polylinker with 21 unique restriction enzyme recognition sites, the vectors are suitable for a range of DNA sequencing and cloning processes.
How can Lambda ZAP 2 Recombinant be distinguished?
What is cos site of phage lambda?
The cos site is a ≈200 bp long segment that is required to both initiate and terminate the packaging of a monomeric genome from concatemeric DNA. The site where terminase introduces staggered nicks to generate the cohesive ends is called cosN (fig. 2).
What is F1 Ori?
The ori is the place where DNA replication begins, enabling a plasmid to reproduce itself as it must to survive within cells (Addgene). F1 is a phage-derived ori that allows for the replication and packaging of ssDNA into phage particles. Plasmids with phage-derived ori’s are referred to as phagemids.
