General description

TransPlex®, a Whole Transcriptome Amplification (WTA) method, allows for representative amplification of nanogram quantities of total RNA in less than 4 hours without 3′-bias. Microgram quantities of amplification product generated from tissue, cultured cells, formalin-fixed samples, or serum are suitable for downstream applications such as qPCR and microarray analyses.

Application

TransPlex® Whole Transcriptome Amplification Kit has been used to synthesize double-stranded cDNA. It has also been used in the amplification of cDNA.
Suitable for use with downstream applications including:
  • qPCR
  • microarray analysis
  • cloning

Features and Benefits

  • Amplification of total RNA in less than 4 hours with less than 30 minutes of "hands-on" time
  • Only 5 ng of starting material required to produce a highly representative library from total RNA
  • Microgram quantities of amplification product generated from intact RNA from tissue, cultured cells, serum, or degraded RNA from formalin-fixed paraffin-embedded samples

Principle

The WTA process involves two steps. In the first step, sample RNA is reverse transcribed with non-self-complementary primers composed of a quasi-random 3′ end and a universal 5′ end. As polymerization proceeds, displaced single strands serve as new templates for primer annealing and extension. The resultant OmniPlex cDNA library, comprised of random, overlapping 100 - 1000 base fragments flanked by universal end sequence, is then amplified by PCR with the universal primer to produce WTA product.

Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.

Aldrich Products

  • For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').

  • For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').

  • For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.

Not Finding What You Are Looking For?

In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the concentration of the dNTPs supplied with the TransPlex® Whole Transcriptome Amplification Kit, Product WTA1?

    The dNTP Mix (D6193) is supplied as 10 mM each.

  4. Is the TransPlex® Whole Transcriptome Amplification Kit, Product WTA1, also applicable for ribosomal RNA and/or small RNA amplification?

    Using the kit as is, Ribosomal RNA does appear to amplify. However, we have not quantitated how well it is amplified.

  5. What is the difference between WTA and WGA?   I use the TransPlex® Whole Transcriptome Amplification Kit, Product WTA1.

    The starting material for WTA is RNA, whereas for WGA it is genomic DNA.  After the RNA is reverse-transcribed into the DNA complement by WTA, the OmniPlex library is formed. This library is in turn amplified by PCR.

  6. Can TransPlex® Whole Transcriptome Amplification Kit, Product WTA1, be used to amplify archival fixed tissue or degraded samples?

    Yes, the WTA kit effectively amplifies degraded RNA, including formalin-fixed and paraffin-embedded samples.

  7. Can TransPlex® Whole Transcriptome Amplification Kit, Product WTA1, be used for downstream applications?

    Upon creation of a cDNA library, quantitative qPCR or microarray analysis may be performed

  8. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
