Product Information
| Description: | Hemicholinium 3 is a compound which blocks the reuptake of choline by the high-affinity choline transporter (ChT) at the presynapse. Hemicholinium 3 is a competitive inhibitor of the high affinity choline transporter (HACU) with a Ki value of 25 nM. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
