Bullseye Pre-stained Protein Ladder, 10-180 kDa

• Ready to use - no boiling necessary
• Stable at ambient temperature
• 2 reference bands - red at ~75kDa and green at ~25kDa
• Use 5-15µl, depending on the size of the wells
• No freeze-thaw involved
• Broad range ladder

Application: The Bullseye Pre-stained Protein Ladder is suitable for visualizing proteins during electrophoresis without staining and for monitoring transfer onto membrane.

The Bullseye Pre-stained Protein Ladder contains 10 prestained proteins, covering a wide range of molecular weights from 10 to 180kDa. It is designed for monitoring protein separated during polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes and for sizing of proteins. The ladder is supplied in protein gel loading buffer and is ready-to-use. No need to heat, dilute, or add reducing agent before loading. One prominent feature of this protein ladder, is that it remains in the liquid state at the storage temperature; therefore, there is not a freeze-thaw cycle involved, making the ladder very stable.

Contents:
0.1~0.4 mg/ml of each protein in 20 mM Trisphosphate (pH 7.5 at 25°C), 2% SDS, 1 mM reducing reagent, 3.6 M Urea, and stabilizer.

Usage:
For each application, 5-15µl is needed, depending on the size of the wells.

Quality Control:
Tested in polyacrylamide gel electrophoresis and Western Blotting.

Storage: -20 °C.

RunBlue SDS Running Buffer (NXB50500) a TEO-Tricine buffer system which provides a separation similar to the MOPS buffer used with BIS-TRIS precast gels. It provides enhanced separation of higher molecular weight proteins. The buffer can be for reduced and non-reduced samples.

RunBlue TGS Blot Buffer(NXB82600) has been specially formulated to provide optimal blot transfer of proteins from RunBlue Precast Gels. Supplied as a concentrate should be diluted by a factor of 10 for use with the RunBlue Dual Run and Blot system or a factor of 20 for use with other blotting methods.

Cytiva 3MM Chr paper is the world's most widely used blotting paper.

This acceptance and usage reflect the high quality, purity and consistency that are relied upon by researchers doing Southern, Northern and Western transfers. 3MM Chr paper is now available in the most widely used sizes. A medium thickness paper (0.34 mm) used extensively for blotting in electrophoresis for lifting of sequencing gels.

GB004
A thick gel blotting paper (1.0 mm), used for wicking purposes only. Provides higher absorbency and more consistent wicking than paper towels. Recommended for applications where fewer layers of gel blotting paper must still ensure a high capacity. Fewer layers of blotting paper reduce the risk of trapping air bubbles. Recommended for capillary blotting of nucleic acids.

GB005
An extra-thick (1.2 mm ), highly absorbent paper recommended for applications where fewer layers of blotting paper must siill ensure a high capacity. Recommended for semi-dry blotting of proteins.

17 Chr
A thick (0.92 mm) and highly absorbent paper.

31 ET
An extremely fast and thick paper (0.5 mm) with a fairly soft surface.

Features and Benefits

• Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind. Ensures that no contamination will occur during the transfer steps
• Manufactured and tested specifically for chromatographic techniques. This ensures the wicking capability and uniformity of capillary action that is important in obtaining clean and even transfers during blotting
• Cytiva 3MM Chr is considered the industry standard for blotting procedures
• Convenient sizes available in sheets precisely cut to the most popular gel and transfer membrane sizes. Allows "out-of-the-box" usage and eliminates sheet-to-sheet variations

3MW is used widely in nucleic acid and protein research for blotting, wicking, spacers, and gel drying due to its purity, quality and consistent results. Uniform capillary action provides even wicking and enables gel transfers to be lifted RELIABLY from glass supports.

Protran nitrocellulose membranes are the most frequently specified transfer media in the world for a wide range of applications. Protran membranes are manufactured using 100% pure nitrocellulose to ensure the highest binding capacity possible. Other membranes referred to as "nitrocellulose" may actually contain large amounts of cellulose acetate, which will lower the protein binding capacity. In addition to high binding capacity, Protran nitrocellulose membranes inherently have very low background. The superior surface properties of the membrane guarantees superior signal-to-noise ratios, without the need for stringent washing conditions. Unlike PVDF membranes, Protran nitrocellulose requires no methanol pre-wetting step. This makes it the membrane of choice for proteins that prefer aqueous environments. Prior to transfer, the membrane is simply wet in water and then in the transfer buffer, with no other necessary pre-treatment steps. Protran membranes exhibit the best handling strangth of all pure nitrocellulose membranes.
Features:

• High binding capacity (80-150g/cm2) of proteins and nucleic acids.
• 100% pure nitrocellulose, with no cellulose acetate added, ensures the highest binding capacity possible.
• Compatible with virtually all standard detection methods.
• Low background - NC surface properties guarantee superior signal-to-noise ratios.
• Triton-free matrix with low extractable levels will support the cell growth essential for colony blotting, plaque lifts, and tissue culture applications.
• Available in many sizes and formats to fit different transfer devices and gel chambers.
