Product Summary
The Quantikine Rat TIM-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure rat TIM-1 in cell culture supernates, tissue homogenates, serum, plasma, and urine. It contains NS0-expressed recombinant rat TIM-1 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural rat TIM-1 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 rat TIM-1.

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.

The recovery of rat TIM-1 spiked to three levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Supernates (n=5) 96 93-99
EDTA Plasma (n=4) 99 84-107
Heparin Plasma (n=4) 102 95-114
Serum (n=4) 102 82-112
Urine (n=4) 103 87-117
To assess the linearity of the assay, samples containing or spiked with rat TIM-1 in each matrix were diluted with Calibrator Diluent and then assayed.

Background: TIM-1/KIM-1/HAVCR
TIM-1 (T cell immunoglobulin and mucin domain 1), also known as KIM-1 and HAVcr1, is expressed on many immune cell types and epithelial cells. It binds to phosphatidylserine (PS), LMIR5/CD300b, TIM-1 (homophilic), TIM-4, IgA, and the glycoproteins of a number of enveloped viruses. Its interaction with PS enables TIM-1 to mediate the phagocytosis and clearance of apoptotic cells. TIM-1 signaling costimulates T cell activation and enhances Th2 cytokine production. TIM-1 serves as a cellular entry receptor for hepatitis A virus, Ebolavirus and Marburgvirus. Polymorphisms are associated with susceptibility to atopy, autoimmunity, and severe hepatitis A virus infection in humans. A soluble form of TIM-1 is elevated in the urine during nephropathy.

    Assay Procedure
    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.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 50 µL Assay Diluent
    4.   Add 50 µL of Assay Diluent to each well.

    5. 50 µL Standard, Control, or Sample
    6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
    7.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

    8. 100 µL Conjugate
    9.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
    10.   Aspirate and wash 5 times.

    11. 100 µL Substrate Solution
    12.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    13. 100 µL Stop Solution
    14.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
