Each package of SmartCheck™ markers includes 2 tubes of 250ul,
allowing less freeze-thaw cycles during product usage thereby
extending the shelf life.

The SmartCheck™ All Blue Regular Range Protein Markers include 10 or
11 pre-stained proteins covering a range of molecular weights from 10
to 180 kDa.* Proteins are covalently coupled with a blue chromophore,
with two enhanced intensity reference bands (at 25 kDa and 72 kDa) to
allow easy visual interpretation.

The SmartCheck™ Tri-Color Regular Range Protein Markers are ready to
use standards with 10, 12, or 13 pre-stained proteins covering a wide
range of molecular weights from 5 to 245 kDa.* Proteins are covalently
coupled with a blue chromophore with two alternate-colored reference
bands (one green and one red band at 25 kDa and 75 kDa respectively).
Tri-Color markers are ideal for western blotting applications, as the
enhanced green and red bands make it easy to identify the orientation
of the blot after transfer.
