Sufficient For 16 pull-down assays
Description ActivX Desthiobiotin-GTP Probe
Quantity 16 x 12.9µg

ActivX GTP Probes feature a desthiobiotin (biotin analog) tag that facilitates selective enrichment and recovery of labeled GTPases allowing identification and profiling of target enzyme classes across samples or to assess the specificity and affinity of enzyme inhibitors.


  • Specific – label only the conserved active-site lysines of nucleotide-binding proteins

  • Compatible – use for in vitro labeling of GTPase enzymes derived from cells or tissues.

  • Flexible – use with Western blot or mass spectrometry (MS) workflows

Recommended for:

Broad enrichment of GTP-binding proteins from tissues, cells and subcellular proteomes; Enrichment of enzymes based on function; Profiling of dozens to hundreds of inhibitor targets.
