Product Information
The ChromoTek His Fab-Trap® Magnetic Agarose consists of an anti-His-tag Fab fragment, which is covalently bound to magnetic agarose beads. It can be used for the immunoprecipitation of proteins fused to the His-tag from cell extracts of various organisms.
| Description | Immunoprecipitation of His-tagged proteins with anti-His-tag Fab-fragment conjugated to magnetic agarose beads. • 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 | 10 ug of recombinant His-tagged protein (~30 kDa) per 25 ul bead slurry |
| Conjugate | Magnetic Agarose beads; ~40 um (cross-linked 6% magnetic agarose beads) |
| Elution buffer | 2x SDS-sample buffer (Lämmli), 200 mM glycine pH 2.5 or 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, 0.2% 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 |
