Substrate studies


PortaCellTec offers three possibilities to measure substrate transporter interactions:

  1. Quantification of substrate uptake with radio-labeled substrates

 
  2. Quantification of substrate uptake with fluorescent substrates  

  3.

Quantification of non-labeled substrate uptake by LC-MS/MS
(we provide this service together with a cooperation partner)
New


First Step

Time and concentration dependent uptake of a test item is performed in the absence and presence of a probe inhibitor.




Second Step

Determination of Km and Vmax value: Concentration dependent uptake of a labeled test item to determine the affinity (Km value) and the maximum transport rate (Vmax) of a transporter for a test item.
