What is blotting / hybridization? Blotting of nucleic acid is the central technique for hybridization studies. Double stranded DNA will denature or separate at high temperatures into single strands. When the temperature is lowered, the two strands will anneal because of the base pairing interaction between the complementary strands. If nucleotide sequences are identical or similar, complementar...

Western blot analysis is a widely used technique for protein immunodetection. Its current format, however is unsuitable for multiplex detection of proteins, primarily due to intrinsic limitations of standard organic dyes employed as probes. Quantum dot (QD) semiconductor nanoparticles exhibit significant advantages over organic dyes, including their broad absorption bands, narrow, tunable, and ...

definitive diagnosis of brucellosis is made by isolation of the causative agents, which is a timeconsumingprocedure. to evaluate the efficacy of dot-elisa for detecting brucellae in clinical samples, 94different specimens taken from animal origin were cultured on brucella selective culture media and colonieswere identified biochemically. the specimens were also examined after centrifugation by ...
