PR1MA One-Step RT-PCR Kit
  • Convenient cDNA synthesis and PCR in a single tube from 1 pg total RNA
  • Formulated for highly specific and sensitive RT-PCR from any RNA templates
  • Incorporates thermostable reverse transcriptase and Hot-Start Taq for preparation at room temperature


The PR1MA One-Step RT-PCR Kit has been formulated for cDNA synthesis and subsequent PCR in a single tube for end-point analysis. This latest generation RT-PCR Kit consists of an MMLV-derived, thermostable Reverse Transcriptase (45°C to 55°C), an advanced RNase Inhibitor and PR1MA Hot Start Taq for ultra-sensitive one-step RT-PCR from as little as 1pg total RNA starting material.

The optimized buffer chemistry allows for efficient reverse transcription and PCR of problematic sequences with significant secondary structure (such as GC-rich targets). The PR1MA One-Step RT-PCR Kit is ideal for determining the presence or absence of RNA templates and quantifying expression through qualitative analysis of RNA transcription levels. The kit also efficiently synthesizes double-stranded cDNA for subsequent gene expression analysis.

PR1MA™ qMAX™ cDNA Synthesis Kits

PR1MA™ now offers two cDNA Synthesis Kits, to meet a range of requirements.
 

The original cDNA Synthesis Kit is a 2-tube format for easy reaction setup and is ideal for 4 pg to 0.5 µg of input RNA. One tube includes our exceptionally stable Reverse Transcriptase combined with a potent RNAse inhibitor, and the other tube contains a 5X reaction buffer with an optimal mixture of anchored oligo (dT) primers and random hexamers to produce a non-biased population of cDNA. 
 

The 1st Strand cDNA Synthesis Flex Kit includes four components: a high-capacity Reverse Transcriptase, an optimized 5X buffer, separate solutions of oligo (dT) primers, and random hexamer primers. This multi-component format is ideal for 10pg to 2.0µg of input RNA and allows for greater flexibility in assay design.

Cas9 Nuclease 
Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide bacteria and archaea with adaptive immunity against viruses and plasmids by using CRISPR RNAs (crRNAs) to guide the silencing of invading nucleic acids. The CRISPR system consists of a short non-coding guide RNA (sgRNA) made up of a target complementary CRISPR RNA (crRNA) and an auxiliary transactivating crRNA (tracrRNA). The sgRNA guides the Cas9 endonuclease to a specific genomic locus via base pairing between the crRNA sequence and the target sequence, and cleaves the DNA to create a double-strand break. The location of the break is within the target sequence 3 bases from the NGG PAM (Protospacer Adjacent Motif). The PAM sequence, NGG, must follow the targeted region on the opposite strand of the DNA with respect to the region complementary sgRNA sequence (Fig.1).

Intact Genomics Cas9 Nuclease is the purified recombinant Streptococcus pyogenes Cas9 enzyme containing a nuclear localization signal (NLS) at the C-terminal for targeting to the nucleus. This enzyme is designed to perform CRISPR/Cas9-mediated genome editing. The physical purity of this enzyme is â¥98% as assessed by SDS-PAGE with Coomassie® blue staining.

Application:

  • First strand cDNA synthesis for PCR
  • Construction of cDNA libraries
  • Generation of probes for hybridization

EasyScript cDNA Synthesis Kit is a complete system for the efficient synthesis of first strand cDNA from RNA templates. The recombinant RNasin Ribonuclease Inhibitor, supplied with the kit effectively protects RNA template from degradation.

The kit is also supplied with both oligo(dT) and random primers. The oligo(dT) anneals selectively on the poly(A) tail of mRNA. Random primers do not require the presence of poly(A). Therefore, they can be used for transcription of the 5'-end regions of mRNA. Gene-specific primers may also be used with the kit. The first strand of cDNA can be directly used as a template in PCR.

EasyScript Reverse Transcriptase (RTase) within the kit is a genetically modified form of Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV). Both the EasyScript and EasyScript Plus are RNase H deficient (negative). The enzyme is purified from bacteria host as a single holoenzyme of 71 kDa with the capacity of first-strand cDNA synthesis of template up to 9kb and can be used for routine cDNA synthesis.

Storage: 
Store at -20°C in a frost-free freezer. Multiple freezing and thawing of RNA should be avoided. Keep RNA on ice all the time. It is recommended that the first strand cDNA synthesis is carried out under conditions where RNase contamination has been eliminated.

General Protocol:

RT-PCR reactions should be assembled in a RNA-free environment. The use of "clean", automatic pipettes designated for PCR and aerosol resistant barrier tips are recommended. 
1. Thaw template RNA and all reagents on ice. Mix each solution by vortexing, and centrifuge briefly to collect residual liquid from the sides of the tubes.

3. Incubate at 25°C for 10 minutes if random primer is used. Omit this step if Oligo(dT) primer or sequence specific primer are used.
4. Incubate the mixture at 42°C for 60 minutes.
5. Stop the reaction by heating at 85°C for 5 minutes.
6. Chill on ice. The newly synthesized first-strand cDNA now can be used directly for PCR amplification.

Notes:
1. Isolation of poly(A)+ RNA from total RNA is not mandatory; however, doing so may improve the yield and purity of the final product.
2. RNA sample must be free of contaminating genomic DNA.
3. Unlike the oligo(dT) priming, which usually requires no optimization, the ratio of a random primer to RNA is critical in terms of the average length of cDNA synthesized in the reaction. Increasing the ratio of random primer/RNA will result in higher yield of shorter (~500 bp) cDNA, whereas decreasing this ratio will produce longer products.

4. The synthesized cDNA should be stored at -20°C.
