  • General notes

    Prestained Protein Ladder ab234592 is a three-color protein standard with 10 pre-stained proteins covering a range of MW from 6.5-270 kDa. This prestained protein ladder allows you to monitor protein separation during SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.

    Key product features:

    • Broad range: 6.5-270 kDa
    • Ready to use: The ladder is supplied in the gel loading buffer and is ready to use.
    • Easily identified: Proteins are covalently coupled with a blue chromophore except three reference bands (two orange bands at 30 kDa and 270 kDa and one green band at 52 kDa).

    3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. 2.5 μl per well for general Western transferring.

Applications

Our Abpromise guarantee covers the use of ab234592 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration.

For monitoring protein transfer onto membranes and sizing of proteins on WB. Recommended loading amounts: 2.5 μl

SDS-PAGE Use at an assay dependent concentration.

For monitoring protein migration and sizing of proteins on SDS-PAGE. Recommended loading amounts: 3-5 ul per well for 15-well or 10-well mini-gel, respectively.

Images

  • SDS-PAGE analysis with ab234592.

    Gel 1: Tris-Glycine 4-20%

    Gel 2: Bis-Tris 4-12% MES buffer.

    The apparent molecular weight (kDa) of each protein has been determined by calibration against unstained protein standards; supplemental data should be considered for more accurate adjustment in different electrophoresis conditions.
