cDNA synthesis kits—SMART technology

cDNA synthesis

SMART (Switching Mechanism at 5' End of RNA Template) is a unique technology that allows the efficient incorporation of known sequences at both ends of cDNA during first-strand synthesis, without adapter ligation. The presence of these known sequences is crucial for a number of downstream applications, including amplification, RACE, and library construction. While a wide variety of technologies can be employed to take advantage of these known sequences, the simplicity and efficiency of SMART technology permits unparalleled sensitivity and ensures that full-length cDNA is generated and amplified.

While a wide variety of technologies can be employed to take advantage of these known sequences, the simplicity and efficiency of SMART technology permits unparalleled sensitivity and ensures that full-length cDNA is generated and amplified.

Minimal RNA sample handling

The entire SMART protocol is performed by one enzymatic reaction, in a single tube. Your precious RNA is subjected to the least possible handling, minimizing potential degradation risks. The protocol is user-friendly and straightforward with no adaptor ligation, no tailing, and no intervening purification steps.

Full-length cDNA enrichment

Because cDNA synthesis is susceptible to interruption by secondary structures in the template RNA, the 5' ends of genes are typically underrepresented in cDNA synthesized by conventional methods. During SMART cDNA synthesis, truncated products resulting from premature termination of the reverse transcription reaction do not incorporate the SMARTer oligonucleotide and consequently are not amplified during PCR. Thus, cDNA created using our SMART technology and amplified by long-distance PCR is enriched for full-length cDNA. Furthermore, because the 5' SMARTer sequence and modified oligo(dT) primer are not added onto genomic DNA or cDNA transcribed from ribosomal RNA, cDNA that is generated using SMART technology is free of sequences derived from these contaminating agents.

Extraordinary sensitivity and high efficiency

One of the greatest advantages of SMART technology is its increased efficiency compared to traditional technologies such as adapter ligation. Its high efficiency and sensitivity enables you to use a very limited quantity of starting material, such as microdissected tissues, laser-captured cells, biopsy samples, etc. As little as 1–2 ng of total RNA is sufficient for generating a highly representative cDNA pool for different downstream applications.

Single-step procedure

During first-strand SMARTer cDNA synthesis, known universal primer sequences are incorporated at both ends of the cDNA. Following first-strand synthesis, SMARTer cDNA is immediately available for PCR amplification.

634928 SMARTer® Pico PCR cDNA Synthesis Kit 10 Rxns USD $1415.00

The SMARTer Pico PCR cDNA Synthesis Kit provides a PCR-based method for producing high-quality cDNA from picogram quantities of total RNA. The cornerstone of SMARTer cDNA synthesis is still our unique SMART (Switching Mechanism At the 5' End of RNA Transcript) technology; now with a modified SMARTer II A oligo. This new and improved oligo, combined with SMARTScribe Reverse Transcriptase, provides higher specificity and increased yields. The SMARTer Pico PCR cDNA Synthesis Kit allows you to synthesize high-quality cDNA for array probe generation, cDNA subtraction, "Virtual Northern" blots, or other applications, from as little as 1 ng of total RNA at extremely low concentrations (or in diluted samples). It is especially useful for researchers who have limited starting material, such as RNA derived from laser-capture microscopy samples, cells sorted by flow cytometry, or other extremely small samples.
