GoldBand 3-color Low Range Protein Marker (2.7-40 kDa)

Details:

Description

This product consists of 9 highly purified and prestained proteins ranging in molecular weight from 2.7 kDa to 40kDa (2.7,4.2,6.5,10,15,20,25,30,40 kDa), among them, 40 kDa is orange band, 10 kDa is green band. The labeled apparent molecular weight was calibrated by the molecular weight Marker of standard non-prestained proteins. Using this product, the state of protein electrophoresis and the effect of membrane transfer can be dynamically observed. After SDS-PAGE electrophoresis, the color bands were transferred to PVDF membrane and NC membrane. This product is conveniently packaged and is a ready-to-use product, do not heat, dilute or add reducing agents! After the prestained protein is combined with the dye, in different buffer systems, there is displacement. this product is only for reference when judging the molecular weight of the target protein.

 Features

  • Bright color - three color predye, each strip average concentration of 2.5 μg
  • Lower amount of this product into the gel hole - mini-gel: 3-5 μL; Western blotting: 1.5-2.5 μL
  • Stable performance - 50℃ for 20 h, no degradation
  • Long shelf life - can be stored at -15℃ ~ -25℃ for two years

Applications

  • Protein migration is monitored during SDS-PAGE electrophoresis
  • Monitor protein transfer to the membrane after Western blotting
  • Protein size analysis on SDS-PAGE and Western blotting
