Ladders & Agaroses

The Small RNA Prestain Marker Plus consists of six prestained single-strand (blue and red) nucleic acids (apparent molecular weights are 20, 30, 40, 50, 75 and 100 bases) and it is visible during electrophoresis. The Small RNA Prestain Marker Plus is suitable for monitoring denaturing polyacrylamide gel electrophoresis and blotting onto membranes. The apparent sizes of bands in Small RNA Prestain Marker Plus are in excellent agreement with sizes of non-stained RNAs, 20, 30, 40, 50, 75 and 100 bases in length (about 95% accuracy). The Small RNA Prestain Marker Plus is supplied in a ready-to-use mixture and doesn't require heating or addition of a denaturing agent before use.

The RNA Prestain Marker High is a RNA ladder for precise sizing of RNA molecules in denaturing agarose gels. The RNA Prestain Marker High is a visible molecular weight marker for ssRNA, consisting of six colored (blue and purple) nucleic acids. The six colored bands (apparent molecular weights are 200, 500, 1,000, 2,000, 4,000 and 8,000 bases) are suitable for monitoring denaturing agarose gel electrophoresis and blotting onto membranes. The RNA Prestain Marker High shows the same mobility as that of the RNA Marker High (Cat # R0003) on denaturing agarose gel electrophoresis (>90% accuracy, see table 1). The RNA Prestain Marker High is supplied in a ready-to-use mixture without requiring heating or the addition of a denaturing agent before use.

The Small RNA Marker for Small RNA consists of colored (Blue) and DIG labeled six single strand nucleic acids, the apparent molecular weights of which are 100, 75, 50, 40, 30 and 20 bases of RNAs. This marker is suitable for monitoring denaturing polyacrylamide gel electrophoresis and for immunodetection with anti-DIG antibody.

The Protein MultiColor Marker consists of nine prestained proteins. Each of them are stained red, blue, purple, green or orange, ranging in apparent molecular weight from approximately 8 kDa to 230 kDa. Protein MultiColor Marker is suitable for visualizing proteins during electrophoresis without staining and for monitoring electrophoretic transfer onto membranes. The protein concentrations are optimized to give uniform band intensities.

The Protein MultiColor Marker, low M.W. range consists of seven prestained protein standards, Blue, Red, Green and Purple, ranging in appropriate molecular weight from 2 kDa to 46 kDa. The marker is suitable for monitoring gel electrophoresis and electrophoretic transfer onto membranes. The protein concentrations are optimized to give uniform band intensities.

The DynaMarker Prestain Marker for RNA High is a RNA ladder for precise sizing of RNA molecules in denaturing agarose gels. It is a ready-to-use mixture that does not require heating or addition of a denaturing agent before use. It has the added advantage of containing pre-stained single-strand nucleic acids that are visible during electrophoresis. The apparent sizes of bands in the DynaMarker Prestain Marker for RNA High are 200, 500, 1,000, 2,000, 4,000 and 8,000 bases in length.
