Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase. Recommended alternatives for this product can be found below, as well as customer reviews and Q&As.

Our Abpromise guarantee covers the use of ab3328 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

|IHC-P||Use a concentration of 1 µg/ml.|
機能The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides. Replacement of PSMB6 by PSMB9 increases the capacity of the immunoproteasome to cleave model peptides after hydrophobic and basic residues.
配列類似性Belongs to the peptidase T1B family.
発生段階Highly expressed in immature dendritic cells (at protein level).
翻訳後修飾Autocleaved. The resulting N-terminal Thr residue of the mature subunit is responsible for the nucleophile proteolytic activity.

Western blot of proteasome 20S LMP2 in 50 ug mouse embryo fibroblast cell extract using ab3328.
ab3328 (1µg/ml) staining Proteasome 20S LMP2 in human heart using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of nuclear and cytoplasmic cell compartments.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers citrate pH6.1/ EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human brain tissue (neurons in HIV encephalitis) sections labelling LMP2 with ab3328 at 1/1000. Immunofluorescence staining for LMP2 shows colocalization with the neuronal marker NeuN. LMP2 is present in granular deposits in the parikaryon. Scale bar = 10 μm.
