Protein Molecular Weight Markers

AMRESCO Protein molecular weight markers are available in a variety of different formulations to provide you with maximum versatility and accurate size estimation.

Precise™ Protein Molecular Weight Marker

7 bands ranging from 15.0 to 150.0 kDa
exact banding pattern makes this marker ideal for SDS-PAGE and Western blotting

Precise Protein MW Marker was separated on a 4-20% RITE-Gel™ Gradient Gel stained with Coomassie® Brilliant Blue.

BlueStep™ Pre-Stained Protein Markers

BlueStep Markers are ready-to-use, pre-stained molecular weight markers in low, broad, and high range. The colored bands are easily transferable to any membrane, making them ideal for Western blotting. The visible separation also makes the markers useful for monitoring real-time run conditions during electrophoresis.

Protein Molecular Weight Markers

Low Range : 6 bands ranging from 19.0 to 120.0 kDa
Broad Range : 9 bands ranging from 9.0 to 200.0 kDa
High Range : 5 bands ranging from 34.0 to 200.0 kDa

Low Range Protein MW Marker

6 bands ranging from 3.5 to 31.0 kDa
excellent for use in AMRESCO’s NEXT GEL System for separating low molecular weight proteins and polypeptides

AMRESCO’s Low Range protein molecular weight marker was separated on a 16% polyacrylamide gel stained with Coomasie® Brilliant Blue. Band sizes: 3.5 kDa, 6.5 kDa, 14.4 kDa, 17.0 kDa, 21.0 kDa, 31.0 kDa.

Wide Range MW Marker

8 bands ranging from 14.0 to 212.0 kDa
pre-mixed marker with supplied denaturing/reducing buffer
ideal for high or low molecular weight applications

Wide Range Protein MW Marker run on a 12% Acryl/Bis™ 37.5:1 (30:0.8) gel and stained with Coomassie® Brilliant Blue R-250. Band sizes: 14.4 kDa, 21.0 kDa, 31.0 kDa, 40.0 kDa, 66.2 kDa, 97.4 kDa, 116.0 kDa, 212.0 kDa.

Mid/Low Range Protein Molecular Weight Marker

7 bands ranging from 15.0 to 150.0 kDa
best suited for polyacrylamide gel concentrations from 8-15% (375:1, Acryl/Bis)

High Range Protein Molecular Weight Marker

5 bands ranging from 40.0 to 212.0 kDa
ideal for polyacrylamide gel concentrations from 6-8% (37.5:1, Acryl/Bis)
