SPARCL™ Kits – added May 12, 2016
Since November, 2015 the staff at LDI have been busy developing SPARCL™ versions of our ELISA kits. SPARCL™ technology (Spatial Proximity Analyte Reagent Capture) was developed by Lumigen Corp. We are very pleased to announce that Lumigen has granted Life Diagnostics exclusive rights to manufacture SPARCL versions of our ELISA kits. Thus far, we have made 35 kits. They are listed on our SPARCL kits webpage. More are in development.

SPARCL™ assays use two antibodies. One is conjugated to HRP, the second to acridan, a chemiluminescent substrate. When HRP and acridan conjugated antibodies both bind to their target antigen they are brought into close proximity. With the addition of hydrogen peroxide, HRP catalyzes oxidation of proximal acridan molecules causing a flash of chemiluminescence that is proportional to antigen concentration. Acridan conjugated antibodies distant from HRP produce no signal. The technology allows  development of rapid, no-wash, homogeneous immunoassays.

In a typical SPARCL™ assay a mixture of acridan and HRP conjugates is first pipetted into wells of a white 96-well SPARCL™ plate. Diluted samples and standards are then added. After a 30-minute incubation the plate is placed into a luminometer. Luminescence is measured after injection of trigger solution containing hydrogen peroxide, into each well. Assuming 15-minutes preparation and 5-minutes analysis time, the entire assay is complete within 50-minutes. This contrasts with ELISA’s that take 2 – 4+ hours, require 2-4 incubations and 1-3 wash steps.

SPARCL assays require a luminometer capable of simultaneous injection (only one injector is required) and measurement of luminescence. A list of suitable luminometers may be found here.

I have been developing ELISA’s since 2003 and have used them extensively for many years prior to that. I spent the last few months developing our SPARCL™ kits. I am very impressed with their simplicity and speed compared to ELISA.
