Application
For SDS-PAGE and protein transfer, the Biotinylated Molecular Weight Standard Mixture contains proteins, which have been biotin conjugated for use as SDS-PAGE standards for the estimation of the molecular weights of blotted proteins.[1] Visualization is accomplished using streptavidin-peroxidase (Cat. No. S2438) and a color development reagent such as 4-Chloro-1-naphthol (Cat. No. C8890), eliminating the need to cut out separate lanes for general protein stains and can be performed simultaneously with immunostaining procedures. These standards may be used with either the Laemmli[2] or the Weber and Osborn[3] SDS-PAGE procedures.
Preparation Note
Each vial is reconstituted with 1 mL of 1x sample buffer (Cat. No. S3401) and incubated for 2-3 minutes at 100 °C.
Other Notes
Contains nine biotinylated proteins (approx 0.1 mg total).
This product contains:
- α2-macroglobulin (equine serum)
- β-galactosidase (E. coli)
- phosphorylase b (rabbit muscle)
- catalase (bovine liver)
- alcohol dehydrogenase (yeast)
- carbonic anhydrase (bovine erythrocyte)
- trypsin inhibitor (soy bean)
- lysozyme (chicken egg)
- aprotinin (bovine lung)

Can I see a picture of this marker? I would like to use it for chemiluminescent wester blotting
1 answer -
The data sheets for Products SDS7B2 and B2787 do not provide a specific recommendation on how long the solutions of these molecular weight marker mixtures can be kept frozen at -20°C. What information can you provide?
1 answer-
Our R&D group recommends that after reconstitution, the solutions should be divided into aliquots and immediately frozen; avoid repeated freeze / thaw cycles. The aliquots should last at least a year at -20°C. Storage at -80°C would even be better, if it is convenient.
