原理 The MK2-Trap is a high quality MK2-binding protein coupled to a monovalent matrix (agarose particles) for biochemical analysis of MK2 and interacting partners.
样品类型 Cell Extracts
特异性 Posttranslational Modifications: MK2-Trap recognizes unphosphorylated MK2 and Phospho-MK2 (Thr222). Specificity on Phospho-MK2 (Thr334) was not tested.
产品特性 MK2-Trap is excellent for fast and efficient one-step isolation of MK2 and its interacting factors from cellular extract. Isolated MK2 protein may be used further for immunoblot analysis, mass spectrometry, and kinase assays.
MK2-Trap utilizes small recombinant alpaca antibody fragments covalently coupled to the surface of agarose beads.
组件 MK2-Trap coupled to agarose beads
试剂未包括 Lysis buffer (CoIP), 10x RIPA buffer, Dilution buffer, Wash buffer, Elution buffer
别名 MK2 (MAPKAPK2 ELISA Kit 摘要)
背景 Mitogen-activated protein kinase-activated protein kinase 2 (MAPKAPK2 / MK2) belongs to the family of serine/threonine kinases. In response to cellular stress it is phosphorylated and activated by MAP kinase p38.
说明

Bead size ~ 90 µm

实验时间 1.5 h
实验流程
  • Robust and versatile tool for biochemical analyses of MK2 proteins
  • Short incubation times (5 - 30 min)
  • Quantitative isolation of fusion proteins and transiently bound factors from cell extracts or organelles
  • Low unspecific binding
  • No contaminating heavy and light chains of conventional antibodies
  • Applicable in Chromatin Immunoprecipitation (ChIP)
样品收集 Harvest cells:
For one immunoprecipitation reaction the use of 10^6 - 10^7 mammalian cells (approx. one 10 cm dish) is recommended. To harvest adherent cells, aspirate growth medium, add 1 ml ice-cold PBS to cells and scrape cells from dish. Transfer cells to a pre-cooled tube, spin at 500 g for 3 min at +4°C and discard supernatant. Wash cell pellet twice with ice-cold PBS, gently resuspending the cells.

Lyse cells
  • 1. Resuspend cell pellet in 200 µL ice-cold lysis buffer by pipetting or using a syringe.
    note: Supplement lysis buffer with protease inhibitors and 1 mM PMSF (not included). optional for nuclear/chromatin proteins: Use RIPA buffer supplemented with 1 mg/mL DNase, 2.5 mM MgCl2, protease inhibitors and 1 mM PMSF (not included).
  • 2. Place the tube on ice for 30 min with extensively pipetting every 10 min.
  • 3. Centrifuge cell lysate at 20.000x g for 10 min at +4°C. Transfer lysate to a pre-cooled tube. Add 300 µl dilution buffer to lysate. Discard pellet.
    note: At this point cell lysate may be put at -80°C for long-term storage. optional: Add 1 mM PMSF and protease inhibitors (not included) to dilution buffer

We recommend that during incubation with the beads the final concentration of detergents does not exceed 0.2% to avoid unspecific binding to the matrix. If required, use more dilution buffer to dilute the supernatant accordingly.
实验流程

Equilibrate beads

  • 4. Vortex MK2_A beads and pipette 25 µL bead slurry into 500 µL ice-cold dilution buffer. Centrifuge at 2.500x g for 2 min at +4°C. Discard supernatant and repeat wash twice.

Bind proteins:
  • 5. Add diluted lysate (step 3) to equilibrated MK2_A beads (step 4). If required, save 50 µL of diluted lysate for immunoblot analysis. Tumble end-over-end for 1 hour at 4°C.
  • 6. Centrifuge at 2.500x g for 2 min at +4°C. If required, save 50 µL supernatant for immunoblot analysis. Discard remaining supernatant.

Wash beads:
  • 7. Resuspend MK2_A beads in 500 µL dilution buffer. Centrifuge at 2.500x g for 2 min at +4°C. Discard supernatant and repeat wash twice.
    optional: Increase salt concentration in the second washing step up to 500 mM.

Elute proteins:
  • 8. Resuspend MK2_A beads in 100 µL 2x SDS-sample buffer.
  • 9. Boil resuspended MK2_A beads for 10 min at 95°C to dissociate immunocomplexes from MK2_A beads. MK2_A beads can be collected by centrifugation at 2.500x g for 2 min at 4°C and SDS-PAGE is performed with the supernatant.
  • 10. optional instead of steps 8 and 9: elute bound proteins by adding 50 µL 0.2 M glycine pH 2.5 (incubation time: 30 sec under constant mixing) followed by centrifugation. Transfer the supernatant to a new tube and add 5 µL 1M Tris base pH 10.4 for neutralization. To increase elution efficiency this step can be repeated.
