mTRAP™ Components

components available for mTRAP™ Assay Kits

Poly T gripNA™ Probe

Poly T gripNA Probe* has been optimized to ensure efficient recovery of mRNA from cell lysates and tissue homogenates. It is supplied lyophilized in the same amounts to provided in the mTRAP Maxi and mTRAP Midi Kits and is stable for 6 months at -20°C.

* Covered under U.S. Patent No. 6,962,906. Purchase includes the right to use for basic research only. Other-use licenses available, please contact your local Technical Services dept.

Streptavidin Beads

Streptavidin Beads are stable, uniform, non-porous spheres bound with highly active streptavidin. They are RNase and DNase free for direct addition to cell or tissue lysates. The one-micron diameter beads bind 10 pmol biotinylated PNA-analog probe per 1 µl of beads and are supplied at ~1% solids in 50 mM Tris, pH 8, 150 mM NaCl, 0.05% sodium azide and 0.1% stabilizing detergent.

mTRAP™ Lysis Buffer

mTRAP Lysis Buffer consists of 200 mM Tris (pH 7.5), 200 mM NaCl, 500 mM GTC (Guanidine Isothiocyanate) and a proprietary mixture of detergents. Store at room temperature; stable for 6 months.


Protease is active in SDS, EDTA, urea and at high temperatures and is supplied lyophilized. Store at -20°C; stable for 6 months.
