The CloneMiner™ II cDNA Library Construction Kit is a second generation CloneMiner™ kit that enables rapid construction of highly representative cDNA libraries without restriction enzyme cloning. This innovative library construction technology combines SuperScript™ III Reverse Transcriptase with Gateway™ cloning technology, resulting in the discovery of previously unobtainable, full-length clones. The kit also avoids the use of time-consuming, inefficient ligation reactions, making library construction faster and offering better representation.

The CloneMiner™ II cDNA Library Construction Kit ensures:
• High primary titers
• Large average insert sizes
• The highest percentage of full-length genes
• Highly efficient cloning of cDNA to multiple destination vectors without the need of restriction enzyme digestion and ligation

How the CloneMiner™ II Kit Works:

• High yields of full-length cDNA: The CloneMiner™ II kit contains SuperScript™ III for generating high cDNA yields. SuperScript™ III Reverse Transcriptase (RT), a proprietary mutant of SuperScript™ II RT, is active at 50°C and has a half-life of 220 minutes. It also has a point mutation that reduces RNase H activity, thereby decreasing RNA degradation during first-strand synthesis and increasing the percentage of full-length genes.

• Gateway™ cloning technology avoids restriction enzyme cloning: Library construction is mediated by Gateway™ Technology, a site-specific recombination system that eliminates the use of restriction enzymes and ligase in cloning. Each cDNA insert is flanked by specific att recombination sites (added during the cDNA synthesis steps) that recombine with complementary att sites present in Gateway™ donor vectors to create entry clones. Entry clones are subsequently recombined with Gateway™ expression vectors to create expression clones, effectively replacing the use of restriction enzymes and ligase. The resulting clones maintain the original orientation and reading frame enabling functional analysis of full-length genes and whole libraries.

How is This Kit Different From the Original CloneMiner™ Kit?
• The new kit incorporates a simplified protocol.
• To ensure high cDNA yields, SuperScript™ II Reverse Transcriptase (RT) has been replaced by SuperScript™ III Reverse Transcriptase.
• To enable reaction setup with fewer pipetting steps, Gateway™ BP Clonase™ Enzyme Mix has been replaced by Gateway™ BP Clonase™ II Enzyme Mix, which contains enzymes and buffer in a single mix.

Frequently asked questions (FAQs)

Do you still offer the SuperScript Full length cDNA Library Construction Kit?

The SuperScript Full length cDNA Library Construction Kit has been discontinued. The alternative is the CloneMiner II cDNA Library Construction Kit, Cat. No. A11180.

What are the benefits of using the Gateway system in your CloneMiner II cDNA Library Construction Kit?

Gateway entry clone cDNA libraries are ready to transfer into suitable destination vectors for gene expression. You do not have to worry about restriction enzyme digestion of cDNA (which can decrease the insert size,) or vector prior to cloning.

What kit would you recommend for making cDNA libraries?

We would recommend using the CloneMiner cDNA Library Construction Kit (Cat. No. A11180) for construction of high-quality Gateway cloning-compatible cDNA libraries without the use of restriction enzyme cloning. This system uses highly efficient recombinational cloning, resulting in a higher number of primary clones compared to standard cDNA library construction methods.

How large of a PCR product can I recombine with a pDONR vector via BP cloning? Does the same apply for TOPO-adapted Entry vectors?

There is no theoretical limit to insert size for a BP reaction with a pDONR vector. Maximum size tested in-house is 12 kb. TOPO vectors are more sensitive to insert size and 3-5 kb is the upper limit for decent cloning efficiency.

How should I clean up my attB-PCR product?

After generating your attB-PCR product, we recommend purifying it to remove PCR buffer, unincorporated dNTPs, attB primers, and any attB primer-dimers. Primers and primer-dimers can recombine efficiently with the Donor vector in the BP reaction and may increase background after transformation into E. coli, whereas leftover PCR buffer may inhibit the BP reaction. Standard PCR product purification protocols using phenol/chloroform extraction followed by ammonium acetate and ethanol or isopropanol precipitation are not recommended for purification of the attB-PCR product as these protocols generally have exclusion limits of less than 100 bp and do not efficiently remove large primer-dimer products. We recommend a PEG purification protocol (see page 17 of the Gateway Technology with Clonase II manual). If you use the above protocol and your attB-PCR product is still not suitably purified, you may further gel-purify the product. We recommend using the PureLink Quick Gel Extraction kit.
