摘要:
A microarray reader (100) comprises a light source (102), beam shaping elements (104) positioned near the light source (102), a moving stage (124) supporting one or more of the light source (102) and beam shaping elements (104), an optical substrate (112) supporting an immobilized microarray, a reaction chamber (116) in contact with the optical substrate (112) and encapsulating buffer solution, a heating/cooling component (118) in contact with the reaction chamber (116), a synchronization circuit, an optical filter (108) and an imaging sensor (106) positioned near the optical filter (108).
摘要:
Embodiments of the present invention relate to a buffer composition for an integrated nucleic acid amplification and hybridization reaction. The buffer comprise about 50-20 OmM of a salt, about 10-30 mM Tris-HCI, about 2-10M Water soluble magnesium salt, about 0.05-1.5% surfactant, about 0.05-0.15 mg/ml stabilizing protein about 50-300 nM of one or more primers, about 20-15 OuM of one or more dNTPs, about 5-15% glycerine, about 0.5-1.5% formamide and at least about 5 unit/ml polymerase.
