3 μl or 5 μl per loading for clear visualization during electrophoresison 15-well or 10-well mini-gel, respectively. 1.5~2.5 μl per well for general Western transferring. Apply more for thicker (> 1.5 mm) or larger gel. The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute, or add reducing agent before loading. Description: The iPro™ Prestained Protein Ladder I, 8 to 180 kDa, is a ready to use three-color protein standard with 10 pre-stained proteins covering a wide range of molecular weights from 10 to 180 kDa (8 to 170 kDa in Bis-Tris (MOPS) buffer and 8 to 170 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 10 kDa and 72 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). The iPro™ Prestained Protein Ladder I is designed for monitoring protein separation during SDS-PAGE electrophoresis, verification of Western transfer efficiency on membranes, (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. Contents: Approximately 0.2~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate, pH 7.5 at 25°C), 2 % SDS, 1 mM 2-mercaptoethanol, 3.6M Urea, and 15 % (v/v) Glycerol). Quality Control: Under suggested conditions,  The iPro™ Prestained Protein Ladder I resolves10 major bands in polyacrylamide gel with appropriate buffers and after Western blotting to nitrocellulose membrane. Storage: Stable at 4°C for 3 months Stable at -20°C for 24 months

Dual Color Prestained Protein Maker III consists of 11 highly purified and pre-stained recombinant proteins. The indicated molecular weight range in Tris-Glycine Gel was 10-200 kDa (~10, ~15, ~20, ~30, ~40, ~55, ~65, ~90, ~110, ~140, ~200 kDa). With orange-red bands at 90 and 30 kDa. rose-red band at 10 kDa, blue bands at the others. Therefore, it is convenient to observe the electrophoretic state of protein dynamically or judge the effect of protein transmembrane. It is suitable as a protein molecular weight standard for SDS-PAGE and Western blot. His-Tagged proteins: Proteins 40, ~90, ~110, ~140, ~200 kDa are His-tagged. When blotted with anti-His antibody, most of the bands show up after ECL. 40 kDa  band is weak, 90 kDa band doesn't show. This is very helpful when the protein marker is used in His-tagged protein purification. Shipping and Storage ConditionsShip with wet ice; Store at -20°C, valid for 12 months after receiving.
