Aptamers and their applications in immunohistochemistry

Immunohistochemistry has helped to make surgical pathology the ‘gold standard’ for tumour diagnosis. Antibodies have been used extensively as the molecular probes; however, there have been issues with their specificity, which is the most critical determining factor in IHC.

Previous reports have suggested that 40-50 % of diagnostic inconsistencies are related to poor antibody selection, cross […]

Aptamer based assay for sensitive detection of antibiotics in food and water samples

Antibiotics have been widely used in human medicine, aquaculture and agriculture to treat serious infectious diseases. However, overuse and misuse of antibiotics in some areas have contributed to the residues of antibiotic contaminants in water bodies and food products such as meat and dairy. This misuse has resulted in generation of super bacteria with tolerance […]
