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.

The 1 kb PLUS™ is composed of 14 individual DNA fragments: 25K, 10K, 8K, 6K, 5K, 4K, 3K, 2.5K, 2K, 1500, 1000, 750, 500, 250 base pairs. This product contains two enhanced bands (3K and 1K bp) for easy reference. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

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.

The BLUEstain™ Low Range Protein Ladder, 2 to 40 kDa is a ready-to-use three-color protein standard with 6 pre-stained proteins covering a range of molecular weights from 2 to 40 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 10 kDa and 40 kDa respectively) when separated on SDS-PAGE.

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