Category: Cell Culture Protocols: Cell Culture Contamination Prevention and Removal Protocols

For both biological and economical reasons, it is important to eliminate mycoplasmas from cell cultures being used for basic research, diagnosis, and biotechnological production. The most commonly used method for elimination, inactivation, or suppression of mycoplasmas in cell cultures is treatment with antibiotics. In general, antibiotic therapies do not result in long-lasting, successful elimination. Also, the cytotoxic properties of antibiotics can cause undesirable side effects on cells. - [Read Mycoplasma Elimination Reagent Protocol]

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

One step extraction for isolation of plant DNA. DNA suitable for amplification by PCR can be produced from leaf material smaller than 0.3 mm2 in less than 20 min & no tube changes. Method was tested on several plant species. Method was found to extract DNA that could be amplified without any further purification or treatment. The isolated DNA was amplified using a universal chloroplast primer set. The method was validated by comparing size of PCR products generated using standard DNA isolation. - [Read One-Step Isolation of Plant DNA Suitable for PCR Amplification]
