Overview

• Convenient – With the ready-to-use Master Mix, the user needs only to add template to the master mix and enzyme in order to set up the reverse transcriptase reaction
• Time Savings – Set up RT reactions in a shorter time since less pipetting steps are required
• Cost Efficient – No need to buy separate enzymes, dNTPs and buffers. All are included with the ready-to-use Master Mix kits
• High Sensitivity and Yield – the optimized Master Mix allows for highly sensitive amplifications with high yields of PCR products
• Robust Enzyme – broad range of working temperatures from 37°C to 60°C. Capable of amplifying difficult templates with a high degree of reproducibility

TruScript Reverse Transcriptase is Available in Three Convenient Formats:

1. TruScript Reverse Transcriptase Kit (Cat.#54440)

This kit contains 5X RT Buffer and a vial of TruScript Enzyme Mix (200 units/µL). This enzyme can be used for reverse-transcription reactions with any user-supplied primers.

2. TruScript First Strand cDNA Synthesis Kit (Cat.#54420)

This is an all-in-one, ready-to-use product for simple set-up of reverse transcription of total RNA (both poly A- or non-poly A-containing transcripts).

The kit contains the 2x Reaction Mix and the TruScript Enzyme Mix. The 2x Reaction Mix contains a blend of buffer, nucleotides and primers (oligo dT and random hexamers) for effective cDNA synthesis from total RNA transcripts.

3. TruScript First Strand cDNA Synthesis Kit for mRNA (Cat.#54400)

This is an all-in-one, ready-to-use product for simple set-up of reverse transcription of messenger RNA (poly A-containing transcripts).

The kit contains the 2x Reaction Mix and the TruScript Enzyme Mix. The 2x Reaction Mix contains a blend of buffer, nucleotides and oligo dT primer for the effective cDNA synthesis from total RNA transcripts or enriched mRNA sample.

Overview

• Detection kits for the BKV/JCV
• Available in TaqMan format for analysis

The BK virus is a member of the polyomavirus family. It has been suggested that this virus may be transmitted through respiratory fluids or urine, since infected individuals periodically excrete virus in the urine. BK viral infections are typically asymptomatic in healthy individuals, however very mild symptoms may appear including mild respiratory infections and fever. Infections with BK virus in immunocompromised or immunosupressed patients are much more severe and may involve renal dysfunction. In fact, in kidney transplant patients the immunosupressive drugs required for the transplant may allow the virus to replicate within the graft, resulting in a disease called BK virus nephropathy (BKVN). The JC virus is a type of human polyomavirus and is very common in the general population, infecting 70 to 90% of humans. Most people acquire JCV in childhood or adolescence. Typically the infection is subclinical and no of consequence in individuals with healthy immune systems. The initial site of infection may be the tonsils or the gastrointestinal tract, and the virus then remains latent in the gastrointestinal tract. JCV can also infect the tubular epithelial cells in the kidneys, where it continues to reproduce, shedding virus particles in the urine. Also, JCV can cross the blood-brain barrier into the central nervous system. JCV is known to cause the usually fatal progressive multifocal leukoencephalopathy (PML) by destroying oligodendrocytes in the brain in immunodeficient or immunosuppressed individuals. The JC and BK viruses are very similar, with their genomes sharing 75% homology. It is however important to differentiate between the viruses due to the differences in pathology and especially the invariably fatal outcome of PML which is only caused by the JC virus.
