描述

The SuperScript® III CellsDirect cDNA Synthesis Kit is optimized for synthesizing first-strand cDNA directly from a mammalian cell lysate without first isolating the RNA. Lysis and reverse transcription are performed in the same tube, and the resulting first-strand cDNA is ready to use in cloning and PCR. For real-time quantitative RT-PCR, see the note below.

Advantages of the SuperScript® III CellsDirect cDNA Synthesis Kit include:

• Compatible with a wide range of mammalian cell types grown under different treatment conditions
• Single-tube format minimizes reagent loss, sample loss, and handling time
• Total lysate volume is used in first-strand cDNA synthesis reaction, providing greater yields with a limited number of cells and allowing for detection of rare transcripts
• SuperScript® III Reverse Transcriptase, with reduced RNase H activity and higher thermal stability, produces high yields of cDNA in the first-strand synthesis reaction, for greater sensitivity and enhanced detection of rare transcripts
• Generates high-quality cDNA for use in a variety of applications, including cloning and PCR
• Simple protocol takes less than 2 hours

How it works
In traditional RT-PCR, RNA is first isolated from cells in a time-consuming procedure that can lead to a loss of material. Using the SuperScript® III CellsDirect cDNA Synthesis System, the cells are lysed and the cDNA is generated from the lysate in a single tube with minimal handling and no sample loss. DNase I is added to eliminate genomic DNA prior to first-strand synthesis. This kit has been optimized for small cell samples, ranging from 10,000 cells down to a single cell (as measured by serial dilution). The use of SuperScript® III Reverse Transcriptase ensures high specificity and high yields of cDNA from small amounts of starting material—as little as 10 pg total RNA. After synthesis, the first-strand cDNA can be amplified with specific primers by PCR without intermediate organic extractions or ethanol precipitations.
