• 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 3 500 to 38 000) use seven separate proteins with five different colors.

Faster and simpler identification of proteins

These 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.

A mixture of individually colored proteins

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).
