New Products: Protein Ladders

Request a FREE 20ul protein ladder sample (10-180 kDa)


Introducing Proteintech's new range of Prestained Protein Markers (10-180 kDa)  and Broad Range Prestained Protein Markers (3-245 kDa).

- Convenience – One stop shop for your Western blotting needs.

- Great value – Same performance as leading competitors for better price. 

- Versatile – From small to husky proteins, our ladders can fill your Western blotting needs.  

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.

SDS-PAGE band profile of Prestained Protein Ladder*Available as a free sample for a limited time*

Catalog number: PL00001

Resolution of the prestained protein ladder in a 10-20% Tris-glycine gel (SDS-PAGE). The image shows the migration pattern in the gel and after transfer to a PVDF membrane.

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.
