A range of illustra deoxynucleotides, high purity nucleotides for a range of operations including amplification, dideoxy sequencing, labeling, mutagenesis, cDNA synthesis, and expression profiling. The nucleotides are free from DNase, RNase, and nicking enzyme activity and have greater than 99% triphosphate purity (by HPLC) for excellent performance and consistency. Supplied buffer-free in ready-to-use solutions, and in multiple formats. They are functionally tested for long PCR and sequencing.
