Pre-stained Protein Ladder [X10126]

X10126 is a ready-to-use pre-stained protein ladder containing 10 recombinant proteins (25-400 kDa). Features: Four dyes produce vivid bands (mostly blue; 400 kDa red, 70 kDa orange-red and 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 X10126 X-biotechTM Pre-stained Protein Ladder is a ready-to-use pre-stained mixture of 10 recombinant proteins ranging from 25 kDa to 400 kDa. Four 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 three reference bands: 400 kDa (red), 70 kDa (orange-red) and 25 kDa (green).

Important Information

  • X10126 contains 10 protein bands of 25, 45, 70, 100, 130, 160, 200, 250, 300, and 400 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.

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.
