Precision Plus Protein Standards

Precision Plus Protein standards offer the ultimate precision and clarity in protein standards for electrophoresis and blotting. Our top-of-the-line standards provide precise molecular weight markers ranging from 10 to 250 kD without any mobility shifts. Precision Plus Protein standards are recombinant proteins of even molecular weight increments, whether you choose them prestained or unstained. Precision Plus Protein standards are ready to load with sample buffer. The 25, 50, and 75 kD bands are of greater intensity, serving as reference bands.

• Migrate consistently to precise positions without mobility shifts. Proprietary staining method enables prestained standards to be used for accurate molecular weight estimations
• Blended with loading buffer for optimal resolution and convenience, adding certainty to your experiment and saving you time
• Available in unstained, all blue, and dual color options, all with reference bands at 25, 50, and 75 kD
• Unstained standards contain an integral amino acid Strep -tag sequence with a high binding affinity to StrepTactin conjugates. This unique detection system allows precise molecular weight determinations directly on western blots
