Product Information
The ChromoTek His Fab-Trap® Agarose Kit consists of an anti-His-tag Fab-fragment, which is covalently bound to agarose beads. It also contains lysis, wash, and elution buffers that can be used for the immunoprecipitation of His-tagged proteins from cell extracts of various organisms.
| Description | The His Fab-Trap® Agarose Kit contains His Fab-Trap® agarose, lysis, wash, and elution buffers for efficient immunoprecipitation of His-tagged proteins.  • Fast, reliable & efficient one-step immunoprecipitation  • Ready-to-use  • Low background  • Stable under harsh washing conditions  • Suitable for downstream mass spec analysis • Works in samples from: mammals, plants, yeast, etc.  | 
| Applications | IP, Co-IP | 
| Specificity/Target | Binds specifically to the His-tag (also known as hexahistidine or His6-tag) fused to a protein of interest at N-, C- or internal position. Please note that the affinity is highest for a C-terminal fusion (dissociation constant KD of 10 nM for a C-terminal His-tag and 220 nM for an N-terminal His-tag). | 
| Binding Capacity | 25 ug of recombinant His-tagged protein (~30 kDa) per 25 uL bead slurry | 
| Conjugate | Agarose beads; ~90 um (cross-linked 4% agarose beads) | 
| Elution buffer | 2x SDS-sample buffer (Lämmli), 200 mM glycine pH 2.5, 100 µM His-Peptide | 
| Wash Buffer Compatibility | 2 M NaCl, 5 mM DTT, 5 mM β-mercaptoethanol, 5 mM TCEP, 2% NP40, 2% Triton X-100, 0.1% SDS, 5 M Urea | 
| Type | Fab-fragment | 
| Class | Recombinant | 
| Host | Mouse | 
| Affinity (KD) | 10 nM for a C-terminal His-tag and 220 nM for a N-terminal His-tag | 
| Compatibility with mass spectrometry | The His Fab-Trap® is optimized for on-bead digestion. For the application note, please click here: On-bead digest protocol for mass spectrometry  |
