NeoPRO 10 Prestained Protein Ladder (11 to 180 kDa)
Description
NeoPRO 10 Prestained Protein Ladder (11 to 180 kDa) is a combination of 10 prestained proteins with molecular weights ranging from 11 to 180 kDa. The recombinant proteins are covalently coupled to chromophores, with blue bands and two reference bands: a green band at 25 kDa and a red band at 75 kDa.
The ladder tracks protein size and separation during SDS-polyacrylamide gel electrophoresis (SDS-PAGE), enables approximate protein size estimation, and validates Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes.
Product Features
- 10 prestained recombinant proteins spanning 11 to 180 kDa.

Guide for Molecular Weight Estimation (kDa)
Refer to the NeoPRO 10 Prestained Protein Ladder (11 to 180 kDa) patterns under the relevant electrophoresis conditions.

Important Notes
The molecular weight of each protein (kDa) was measured against an unstained protein ladder under each electrophoresis condition. Additional data should be considered for a more accurate adjustment.
