    Molecular Biology Methods

    1. Isolation and Purification


    Well-prepared nucleic acids are critical to your experiments and research, so how you isolate and purify your samples is important. Multiple methods exist for disrupting the cells, removing debris, capturing your sample, removing contaminants, and eluting the sample for use in downstream applications. Find products for isolation, extraction, purification, and more to complete this step of your process.

    2. Labeling and Detection


    Tags or labels, called probes, are added to nucleic acids to enable detection or purification. Labels may include radioactive phosphates, biotin, fluorophores, and enzymes. Fluorescent in situ hybridization (FISH) is used to identify specific DNA sequences and tests can also be performed for pathogen detection. Find labeling and detection kits, spectrophotometers, fluorometers, and more below for your nucleic acid work.

    5. Transfection


    Mimicking natural viral processes, transfection artificially introduces nucleic acids to cells, producing various chemical, biological, or physical changes. Although the term transfection was originally used to describe the uptake of viral nucleic acid from a prokaryote‑infecting virus or bacteriophage, the term currently refers to any artificial introduction of foreign nucleic acid into a cell. Search for transfection reagents, electroporation supplies, and more to help effectively conduct your transfection procedures.
