Zymo Research Corporation ZR 50 bp DNA Marker™ (Ready-to-load) (50 μg/ 600 μl)
The 50 bp DNA marker consists of plasmid DNA that has been digested with endonucleases to yield 12 defined fragments that range in size from 50 - 200 bp. The intensity of the 300 bp band is increased as an identifier. All fragments have 4-base, 5 overhangs.
New England Biolabs, Inc. Rapid™ PNGase F (non-reducing format) – 50 reactions
Developed for proteomic applications, Rapid PNGase F (non-reducing format) enables complete and rapid deglycosylation, while preserving disulfide bonds. This facilitates high throughput proteomics applications and methods for antibody characterization by mass spectrometry, such as intact mass analysis. Rapid PNGase F (non-reducing format) combines the advantages of Rapid PNGase F (fast processing time), with non-reducing conditions, preserving quaternary structure.
- Complete deglycosylation of antibodies and immunoglobulin fusion proteins in 15 minutes
- No reducing agents in the formulation, samples remain intact following deglycosylation
- Recombinant enzyme; guaranteed endoglycosidase F1, F2 or F3 free
- All reaction components are compatible with HPLC and mass spectrometry analysis
- Optimal activity and stability for up to 12 months
Rockland Immunochemicals Diamond Ready-to-Use DNA Ladder 250-10Kbp - MB-204-0500
Diamond Ready-to-Use DNA Ladder 250-10Kbp is 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 of similar size.
