QC147, Quantikine Immunoassay Control Set 612 for Human Progranulin - Please Inquire
The Quantikine Human Progranulin immunoassay is a 4.5 hour solid phase ELISA designed to measure Progranulin in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human Progranulin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural Progranulin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human Progranulin.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
Serum, EDTA Plasma, Heparin Plasma, Urine, Human Milk
Cell Culture Supernates, Saliva
The recovery of Progranulin spiked to levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Media (n=4)
EDTA Plasma (n=4)
Heparin Plasma (n=4)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Progranulin were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Progranulin, also known as proepithelin and PC cell-derived growth factor (PCDGF), is a secreted, glycosylated protein with multiple repeats of the granulin/epithelin motif.
Refer to the product for complete assay procedure.
Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

Read what people are saying who have used Human Progranulin Quantikine ELISA Kit.
We used device loading with cells that can release progranulin. After certain time in in vivo we explant device and collect culture supernatant for the measurement of progranulin. The kit standard curve was very good as R2 was 1. We can easily detect in our samples.
