GBLI-2 | CAS#N/A | bioluminescence probe

MedKoo Cat#: 130105 | Name: GBLI-2

Description:

WARNING: This product is for research use only, not for human or veterinary use.

GBLI-2 serves as a bioluminescence probe for imaging of tumors, specifically granzyme B activity, during immunotherapy treatments. GBLI-2 consists of the mouse granzyme B tetrapeptide IEFD substrate that, through a self-immolative group, was conjugated to D-luciferin. For CT26 murine colorectal carcinoma in mice, GBLI-2 successfully correlated to the amount/level of granzyme B-expressing CD8+ T cells in tumors.
