Rainbow Molecular Weight Markers, low-range Mr 3500 to 38000, seven separate proteins with five different colors (250 µL, 50 minigels)

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