RNAimage Kits

For mRNA Differential Display with three one-base anchored oligo-dT primers and rationally designed arbitrary 13mers.

These kits feature the latest generation of isotopic mRNA Differential Display technology (U.S. Patents 5,262,311; 5,599,672; 5,665,547; 5,965,409 and pending patents). Each kit contains all the reagents needed for differential display except RNA samples, Taq DNA polymerase, and -[33P] dATP. The MessageClean« is also highly recommended prior to differential display to remove trace amounts of DNA contamination from RNA samples.

The major improvements over the previous RNAmap technology are: (1) Optimized primer length ensures excellent reproducibility and maximized coverage of expressed genes. (2) One-base anchored primers minimize the redundancy of the displayed cDNA and simplify the reverse transcription reactions. (3) Attached HindIII site to the primers facilitates the manipulation of the cDNA after cloning.

See Technical Notes Section for further discussion on primer design, calculation of coverage, comparison of DD to other methodologies, and false positives.

All kits are shipped on dry ice via overnight delivery. A detailed step-by step protocol is included.

Schematic representation of mRNA Differential Display using RNAimage« Kits.

Three one-base anchored oligo-dT primers with 5' HindIII sites are used in combination with a series of arbitrary 13mers (also containing 5' HindIII sites) to reverse transcribe and amplify the mRNAs from a cell. Note the primer selectivity is provided by the 3' bases. See Technical Notes for more detailed information on the optimal primer designs for differential display.
Differential Display using an RNAimage« Kit.

Four RNA samples from rodent fibroblast (One normal, three tumorigenic) were compared by differential display using three different one-base anchored oligo-dT primers in combinations with three arbitrary 13mers. Note the excellent reproducibility and primer selectivity. The arrow indicates a candidate for tumor-specific gene expression.

RNAimage Kits 2-10 contain all the components of Kit 1, but each has 8 different arbitrary 13mers (H-AP9 to H-AP80).

Choosing Kits: One could start with any RNAimage Kit since the sequences are random and designed to be maximally different from one another, but to ensure a maximum coverage, multiple kits may be needed (See Technical Notes).
