Description

A unique combination of a number of proprietary plasmids digested with appropriate restriction enzymes and PCR products to yield 13 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 250-10,000 base pairs. The 1K and 3K bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

Description

The BLUEstain™ 2 Protein ladder is a three-color protein standard with 13 prestained proteins, covering a wide range molecular weights from 3.5 to 245 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-glycine buffer). 


The BLUEstain™ 2 Protein ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute or add reducing agent before loading.

Description

ProGlow™ Western Blot Protein Ladders are designed for Western blots. ProGlow™ ladders can be used to monitor electrophoresis progress and to visualize protein standard bands directly on X-ray film or digital analytical equipment. ProGlow™ ladders consist of eight recombinant proteins in the range of 12-90 kDa. The 70 kDa protein is a prestained marker used for monitor of the electrophoresis process and evaluation of Western transfer efficiency. The other seven markers can bind to human, mouse, rat, goat, sheep and rabbit IgG with their IgG binding site, allowing direct visualization of markers on the X-ray film after ECL development.
