- iScript Reverse Transcriptase (RT)
Finally, we will synthesize cDNA using a kit (Life Sciences).
Furthermore, EasyScript™ RTase contains an additional fidelityenhancing subunit which drastically enhances accuracy in reverse transcription.
EasyScript™ cDNA Synthesis Kit contains all materials required for first-strand cDNA synthesis, with the choice of using either Oligo (dT) and/or Random Primers.
5. After cDNA synthesis is complete, dilute samples to 100 µl each by adding 80 µl of RNase-free water. Samples are stable at -20°C or 4°C for a few weeks.
RT reaction is also called first strand cDNA synthesis.
Currently, clinical laboratories world-wide are using different commercially available kits, based on different primers and enzymes, for the synthesis of cDNA. This can potentially influence the results and consequently the detection of MRD. Yet, no study is available comparing these kits in order to define whether these are suitable for the detection of BCR-ABL1 at the MMR level. In this study, we compare six commercially available cDNA synthesis kits (Table ), for the identification of the most suitable kit for use in a CML MRD assay. For each kit, the manufacturers’ protocols are used with BCR-ABL1/ABL1 samples at 0.32%, 0.032% and 0.0032%, followed by the Europe Against Cancer (EAC) protocol for the detection of BCR-ABL1 and ABL1 gene using the TaqMan® method. The results are analysed and scored according to failure rate, linearity and ABL1 copy number.
Accurate and sensitive testing for the detection of abnormal transcripts, allows the correct stratification and treatment of patients. Hence, the use of a suitable kit for the cDNA synthesis is of great importance. This study provides a comprehensive point of reference for clinical laboratories in an attempt to optimize BCR-ABL1 detection. We propose that the Invitrogen SuperScript® III Reverse Transcriptase kit is the most suitable, among the ones used in this study, for the cDNA synthesis to be used for the detection of BCR-ABL1 at the MMR level in a CML MRD assay.

To convert RNA into cDNA. You will use a protein called Reverse Transcriptase, which is a polymerase that synthesizes DNA from RNA. The reaction requires primers, which can be either oligodT (annealing to polyA tails of mRNA) or random hexamers; the kit used here contains both kinds); nucleotides for DNA synthesis (dNTPs); MgC2 and buffers required by the enzyme, which are all present in the 5x Reaction Mix.

The lack of RNase H activity helps
to eliminate RNA degradation during first-strand cDNA synthesis, resulting in better yield and
length of cDNA synthesized.
cDNA Synthesis (Reverse Transcription ..
Therefore, only mRNA
or total RNA templates with 3’-Poly(A) tails are used in cDNA synthesis.
Random Primers are oligonucleotides that anneal at non-specific sites of RNA templates.
Therefore, all forms of RNA can be used in cDNA synthesis.
Gene-Specific Primers are oligonucleotides that are designed to anneal to the specific site
of a target gene.
20 mM Tris-HCl (pH 7.5), 100 mM NaCl, 0.1 mM EDTA, 1 mM DTT, 0.01 % (v/v) NP-40, 50 % (v/v) glycerol.

Both poly(A) + mRNA and total RNA can be used for first-strand cDNA synthesis, but poly(A) + mRNA
may give higher yields and improved purity of final products.

Unlike Oligo(dT) priming, which requires little optimization, the ratio of Random Primers to RNA is often critical in terms of the average length of cDNA synthesized.
