More Details

I don’t have the correct wavelength filter, will the assay still work?

Typically if you are within ± 20 nanometers the assay will still work, but have slightly reduced sensitivity. Some assays have a narrower peak than others, call our tech support for a spectrum to verify.

I don’t have a 96-well plate, will the assay kit work in a 384 well plate, cuvette, etc?

Yes, the assay can be used in any standard plate and cuvette. Simply adjust the total reaction volume to your container. For 384 well use 50 μL, for a cuvette use 500 μL or 1 mL.

Does the assay kit work in particular species?

Yes, this assay works in all species.

How do I prepare cell or tissue samples for assays?

Please refer to the protocol for sample preparation:
Blood samples: Serum and plasma should be diluted 2-5 fold.

Tissue: Prior to dissection, rinse tissue in Tris buffered saline (pH 7.4) to remove blood. Homogenize tissue (50 mg) in 200 μL 50 mM Tris buffer (pH 7.5). Centrifuge at 14,000 x g for 10 min at 4°C. Remove supernatant for assay.

Cell lysate: Collect cells by centrifugation at 2,000 x g for 5 min at 4°C. For adherent cells, do not harvest cells using proteolytic enzymes; rather use a rubber policeman. Homogenize or sonicate cells in an appropriate volume of cold 50 mM Tris buffer (pH 7.5), approximately one million cells per mL. Centrifuge at 14,000 x g for 10 min at 4°C. Remove supernatant for assay. All samples can be stored at -80 to -20°C for at least one month.

Can I store unused reagents for future use?

Yes, unused reagents can be stored according to the assay protocol. Repeated freeze/thaw cycles of reagents should be avoided. Since Assay Buffer is very light sensitive, always keeps buffer in the dark (amber bottle or tube) as much as possible for long term usage.

Do I need to use a standard or standard curve with each assay run?

Yes, it is highly recommended.
