Trevigen’s Molecular Biology products were developed for use in our labs, and routinely used by our research and development group. 25X PBS is economical for routine use in ELISA, Immunocytochemistry, and Western Blots. The DNA electrophoresis accessory, Orange G loading dye, is ideal for PCR applications with a migration range of 10-20 nucleotides and does not require refrigeration. Three types of highly purified genomic DNA (10 mg/ml) are qualified for Northern, Southern, probe array, and dot blotting procedures with a fragment size range of 80–500 base pairs. Trevigen’s Terminal deoxynucleotidyl Transferase (TdT) is highly purified and qualified for in situ DNA labeling.
