| Bioactivity | Ac-ANW-AMC is a fluorogenic substrate for immunoproteasome. Ac-ANW-AMC can be used to measure β5i activity (Ex=345 nm, Em=445 nm)[1][2]. |
| Target | β5i |
| Invitro | Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs)[2].1. For the proteasome activity assay, cells are lysed in the proteasome activity lysis buffer. 2. Cells are homogenized by passing the lysates 15 times through a 26G×1/2″ needle attached to a 1-mL syringe. 3. The lysates are then centrifuged at 12,000 rpm for 15 min. Protein concentrations of the samples are determined using the Bradford assay. 4. Proteasome activity is determined using model peptide substrates by measuring free Ac-ANW-AMC fluorescence on a TECAN infinite m200 fluorometer. 5. The fluorescence unquenched after hydrolysis by proteasomes is monitored every three minutes at 345 nm excitation and 445nm emission wavelengths at 30°C. Note: Each sample is assayed in triplicate. |
