All oligonucleotide synthesized at Bio-Synthesis is quality check by using either MALDI-TOF mass spectrometry, analytical HPLC,or polyacrylamide gel electrophoresis (PAGE) analysis. Final yields are determined using UV absorbance at OD260 In addition, we perform custom formulation and quality control tailored to meet your specific requirements.
Quality Control: Analytical HPLC, Gel eletrophoresis, and MALDI-TOF Mass Spectrometry
Delivery times: 5-7 Working days
Packaging: Dried
Shipping conditions: Room temperature
Storage conditions: -20 oC to -70 oC
Oligonucleotides are stable in solution at 4 oC for up to 2 weeks. Properly reconstituted material stored at -20 oC should be stable for at least 6 months. Dried DNA (when kept at -20 oC) in a nuclease-free environment should be stable for years.
