Range:

Monitor progress of protein electrophoresis and assess transfer efficiency and molecular weight of blotted proteins without staining. Cytiva Life Sciences™ Rainbow™ Molecular Weight Markers use bright, distinctive colors to allow easier confirmation of transfer to blotting membranes and orientation.

Enhanced to enable faster and simpler identification of proteins on SDS-polyacrylamide gels. The ready-to-load markers provide sharper, more intense bands on gels and blots and have improved band spacing for more accurate molecular weight determination.

  • High intensity, prestained multicolored bands allow distinction of closely related proteins
  • Full-Range Rainbow Markers (Mr 12,000 to 225,000) use ten separate proteins with six different colors
  • High-Range Rainbow Markers (Mr 12,000 to 225,000) use eight separate proteins with six different colors
  • Low-Range Rainbow Markers (Mr 3500 to 38,000) use seven separate proteins with five different colors
  • For use on SDS-PAGE

  • The bright, distinctive colors of the markers allow easier confirmation of transfer to blotting membranes and orientation.
  • Markers are a mixture of individually colored proteins that are combined to produce bands of equal color intensity. Approximate protein concentration is 1 to 2 mg/mL, depending on the product
  • Each 250μL pack size is sufficient for use with 50 minigels (10 × 8cm) or 25 large gels (20 × 20cm)
