Product name Human 20S proteasome (20SP) ELISA Kit
Reactivity Human
Applications ELISA
Applications notes This Human 20S proteasome (20SP) ELISA Kit employs a two-site sandwich ELISA to quantitate 20SP in samples. An antibody specific for 20SP has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any20SP present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for 20SP is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of 20SP bound in the initial step. The color development is stopped and the intensity of the color is measured.
Detection method Colorimetric
SampleType Cell culture supernatants, Other biological fluids, Plasma, Serum
Assay type Sandwich ELISA (quantitative)
Assay duration Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.

Usage notes • Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
Storage instructions The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping Gel pack with blue ice.

Additional Information

Background The number and diversity of subunits contained in the 20S core particle depends on the organism; the number of distinct and specialized subunits is larger in multicellular than unicellular organisms and larger in eukaryotes than in prokaryotes. All 20S particles consist of four stacked heptameric ring structures that are themselves composed of two different types of subunits; α subunits are structural in nature, whereas β subunits are predominantly catalytic. The outer two rings in the stack consist of seven α subunits each, which serve as docking domains for the regulatory particles and the alpha subunits N-termini form a gate that blocks unregulated access of substrates to the interior cavity. The inner two rings each consist of seven β subunits and contain the protease active sites that perform the proteolysis reactions. The size of the proteasome is relatively conserved and is about 150 angstroms (Å) by 115 Å.
