Monitor progress of protein electrophoresis and assess transfer efficiency and molecular weight of blotted proteins.without staining High intensity, prestained multicolored bands allow distinction of closely related proteins. For use on SDSPAGE. These readytoload 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).
