New Products: Protein Ladders

Quality Prestained Protein Markers


Introducing Proteintech's new range of Prestained Protein Markers (10-180 kDa)  and Broad Range Prestained Protein Markers (3-245 kDa).The protein ladders are ready to use and available for next day delivery.

Prestained Protein Marker

Available as a free sample for a limited time

The regular range protein marker is a ready to use three-color protein standard with 10 prestained proteins covering a wide range of molecular weights from 10 to 180 kDa. The prestained protein marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes, (PVDF, nylon, or nitrocellulose) and for estimating the size of proteins.

Broad Range Prestained Protein Marker

The broad range protein marker is a ready-to-use three-color protein standard with 13 prestained proteins covering a wide range of molecular weights from 3 to 245 kDa in Tris-Glycine buffer. The broad range prestained protein marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for estimating the size of proteins.
