Pre-stained Protein Ladder [X10125]

X10125 is a ready-to-use pre-stained protein ladder containing 9 recombinant proteins (25-300 kDa). Features: Three dyes produce vivid bands (mostly blue; 70 kDa orange-red, 25 kDa green in SDS-PAGE); No pre-use preparation (heating/dilution/reducing agents) needed; Molecular weights calibrated against commercial unstained standards. Applications: Monitors SDS-PAGE separation, verifies Western blot transfer (PVDF/nitrocellulose), estimates target protein molecular weight. Shipping & Storage: Shipped at 4–8℃ with ice packs; store at -20℃ immediately upon receipt.

Description

The X10125 X-biotechTM Pre-stained Protein Ladder is a ready-to-use pre-stained mixture of 9 recombinant proteins ranging from 25 kDa to 300 kDa. Three different dyes are bound to the proteins, producing a brightly colored ladder. When separated by SDS-PAGE, most proteins exhibit a blue color, except for two reference bands: 70 kDa (orange-red) and 25 kDa (green).

Important Information

  • ● X10125 contains 9 protein bands of 25, 45, 70, 100, 130, 160, 200, 250, and 300 kDa.
  • ● The indicated apparent molecular weights were calibrated against commercially available unstained protein standards under defined electrophoresis conditions.
  • ● Do not heat the product above room temperature.

Migration patterns of this Protein Ladder indifferent electrophoretic conditions

120系列marker标示图

The apparent molecular weight of each protein (kDa) has been determined by calibration of each protein against an unstained protein ladder in specific electrophoresis conditions.

Migration patterns were determined using commercial gels.
