ProMetric™ TriColor Low Range Protein Ladder, 2 to 40 kDa, 250μl

Description 
ProMetric™ TriColor Low Range Protein Ladder, 2 to 40 kDa, is a ready-to-use three-color protein standard with 6 pre-stained proteins covering a range of molecular weights from 2 to 40 kDa.

Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 10 kDa and 40 kDa respectively) when separated on SDS-PAGE.

ProMetric™ TriColor Low Range Protein Ladder is designed for monitoring protein separation during SDS-PAGE electrophoresis, verification of Western transfer efficiency on membranes (PVDF or nitrocellulose) and for approximating the molecular weight of small proteins.

Features:

•Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil

•Two reference bands — 40 kDa (red) and 10 kDa (green)

•Enhanced band clarity for proteins below 10 kDa

•Versatile application across various gel systems, including Tris-Tricine, Tris-Glycine, and Bis-Tris gels

Storage Buffer

20 mM Tris-phosphate (pH 7.5 at 25°C), 1% SDS, 6 M Urea, and 20% (v/v) DMSO.

Quality Control
Under suggested conditions, ProMetric™ TriColor Low Range Protein Ladder, 2 to 40 kDa, resolves 6 major bands in SDS-PAGE (Tris-tricine-SDS Buffer).

Storage 

4°C for 3 months

-20°C for long term storage
