NOTE 1: AFDye 488 (similar to FITC), AFDye 555 (similar to Cy3), AFDye 647 (similar to Cy5) are analogs of AlexaFluor® 488, AlexaFluor® 555, and AlexaFluor® 647 dyes, respectively.
NOTE 2: IR750 dye is ithe analog of the IRDye® 750 dye.
Protein L is an immunoglobulin-binding protein originally derived from the surface of bacterium Peptostreptococcus magnus. Protein L binds to Ig through the L chain interaction, from which the name was derived. The native Protein L consists of 719 amino acid residues with the molecular weight estimated as 95 kDa by SDS-PAGE analysis. Protein L does not contain any inter chain disulfide loops or disulfide-linked subunits.
Gold Biotechnology Inc VersaLadder™, 100-10,000 bp 500 µL
A unique combination of a number of proprietary plasmids digested with appropriate restriction enzymes and PCR products to yield 19 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 100-10,000 base pairs. The 500, 1.5K 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 of similar size. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.
Biochain Institute Inc 100 bp DNA Ladder Plus, ready-to-use, 250 ug, 0.5 ug per lane, 500 lanes/PK
BioChain provides a series of molecular weight markers, including DNA markers, RNA markers, and protein markers, to accurately determine the size of your DNA, RNA, and protein on the separation gels.
