Push-pull CNS probes

High cut-off probes are ideal for sampling peptides, proteins & cytokines.

Brainlink offer different types of push-pull probes. The cut-off values range from 500 kDa - 3000 kDa. A smaller pore size will give less ultrafiltration fluid loss into the brain and your sample will be "cleaner". Push-pull probes are ideal for sampling large molecules like neuropeptides, proteins and cytokines.
