Product Summary
The Human sP-Selectin Immunoassay is a 1.25 hour solid phase ELISA that measures sP-Selectin in cell culture supernates, serum, and plasma. It contains recombinant human sP-Selectin and antibodies raised against the recombinant factor. It has been shown to accurately quantitate the recombinant sP-Selectin. Results obtained using natural human sP-Selectin showed linear curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural human sP-Selectin.

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.

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: P-Selectin/CD62P
The Selectin family is comprised of three members, E-Selectin, L-Selectin, and P-Selectin. E-Selectin [endothelial leukocyte adhesion molecule-1 (ELAM-1), CD62E] is transiently expressed on vascular endothelial cells in response to IL-1 beta and TNF-alpha. The human and rat proteins share approximately 67% amino acid sequence identity. The mouse and rat proteins share approximately 78% amino acid sequence identity. L-Selectin (Leukocyte Selectin, LAM-1, LECAM-1, LECCAM-1, TQ1, Leu-8, MEL-14 antigen, DREG, lymph node homing receptor, CD62L) is expressed constitutively on a wide variety of leukocytes. Two forms of L-Selectin have been reported, apparently arising as a result of post-translational modifications. Human and mouse L-Selectin share 76% amino acid sequence identity. Human P-Selectin (GMP-140, LECAM-3, PADGEM, CD62P) is expressed by activated platelets and endothelial cells. The extracellular domains of human and mouse P-Selectin share approximately 73% amino acid sequence identity.

    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, samples, and Control 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. 100 µL Standard, Control, or sample
    4.   Add 100 µL of Standard, Control, or sample to each well.

    5. 100 µL Conjugate
    6.   Add 100 µL of Conjugate to each well. Tap the plate gently to mix. Cover with a plate sealer, and incubate at room temperature for 1 hour.
    7.   Aspirate or decant each well and wash, repeating the process twice for a total of 3 washes.

    8. 100 µL Substrate
    9.   Add 100 µL of Substrate to each well. Cover with a new plate sealer, and incubate at room temperature for 15 minutes.

    10. 100 µL Stop Solution
    11.   Add 100 µL Stop Solution to each well. The Stop Solution should be added to the wells in the same order as the Substrate. Read at 450 nm within 30 minutes. Set wavelength correction to 620 nm or 650 nm.
