Extracellular antibodies are ideal research tools for cell-surface proteins.

No permeabilization/fixation because using extracellular antibodies allows you to work with live cells!

Benefits of live cell imaging:
✓ Monitor cell movement
✓ Study protein transport across the cell
✓ Investigate protein internalization

The mammalian melastatin-related transient receptor potential (TRPM) is a subfamily of the TRP family. The family was named after the first member, melastatin (TRPM1), whose gene was identified in metastatic and benign melanomas. The TRPM proteins share structural homology with other members of the TRP superfamily channels; six putative transmembrane domains, and cytoplasmic N-terminus and C-terminus. However, due to their long N-terminus and C-terminus they were also named the long TRP channel family.The TRPM family consists of eight members designated as TRPM1-8 that can be further divided into four pairs: TRPM1 and TRPM3; TRPM2 and TRPM8; TRPM4 and TRPM5; and TRPM6 and TRPM7.
