Push-pull CNS NHP probes

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

Brainlink offer different types of push-pull probes. The cut-off values are 500 kDa (PES), 1000kDa (PES) & 1-3 MDa (PE). 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 peptides, proteins and cytokines.
