    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 x 8cm) or 25 large gels (20 x 20cm)
