YesBlot Western Marker I

Cat#: WM1000
Sales Price$171.00

The WM1000 YesBlot Western Marker I is a ready-to-use mixture with ten IgG-binding proteins covering a wide range of molecular weights from 15 to 200 kDa in TrisGlycine buffer. YesBlot Western Marker I performs dual functions: 

  1. Contains 4 pre-stained proteins (10, 25, 45 and 70 kDa) for monitoring protein separation during SDSPAGE, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for approximating the protein size
  2. Ten IgG-binding proteins can be immuno-detected on film or by CCD imaging

YesBlot Western Marker I can be used with chemiluminescent, fluorescent, chromogenic and other detection systems. In addition, YesBlot Western Marker I has two reference bands with enhanced intensity (at 30 kDa and 80 kDa). The marker is supplied in the gel loading buffer and is ready to use. Do NOT heat, dilute, or add reducing agents before loading.
