Challenges and Solutions for Developing New Monoclonal Antibodies

Unprecedented advances in medicine are delivering remarkable results for some patients. Recent approvals of CAR T therapies and new approaches in regenerative medicine, for example, exemplify Monoclonal antibodies (mAbs) used for immunotherapy stimulate the immune system to mount a response to target antigens. These powerful therapeutics are being used to...

Microsart® AMP Mycoplasma Kit

Mycoplasma are widespread contaminants in cell culture. Given their tiny size (~0.3-0.8 µm), mycoplasma cannot be visualized by microscopy. Cultivation-based detection takes 28 days, and even then, the colonies are difficult to visualize with the naked eye. Mycoplasma-contaminated products present a human health risk, so you must confirm your cell lines are uncontaminated.

Microsart® qPCR kits offer a safe and rapid method for early detection of mycoplasma contamination. It’s fast, highly specific and compliant with international guidelines.
