  • Product overview

    KIM-1 in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of KIM-1 protein in Rat plasma, serum, urine, and cell culture supernatant.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

    KIM-1, also known as Kidney Injury Molecule 1 and Hepatitis A virus cellular receptor 1 homolog (HAVcr-1), or T-cell immunoglobulin and mucin domain 1 (TIM-1) is a 283- amino acid protein that contains an N-terminal immunoglobulin-like domain and is encoded by the HAVCR1 gene. KIM-1 is a single-pass type 1 membrane protein has been identified as a receptor for hepatitis A virus. The TIM gene family participates in host immune response. Urinary KIM-1 levels are elevated in nephropathy and is thought to be a biomarker for renal damage.

  • Research areas

  • Function

    May play a role in T-helper cell development and the regulation of asthma and allergic diseases. Receptor for TIMD4 (By similarity). In case of human hepatitis A virus (HHAV) infection, functions as a cell-surface receptor for the virus. May play a role in kidney injury and repair.
  • Tissue specificity

    Widely expressed, with highest levels in kidney and testis. Expressed by activated CD4+ T-cells during the development of helper T-cells responses.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily. TIM family.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.

Our Abpromise guarantee covers the use of ab223858 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent concentration.


  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.


  • Standard curve comparison between rat KIM-1 SimpleStep ELISA® kit and traditional ELISA kit from leading competitor. SimpleStep ELISA kit shows comparable sensitivity.

  • Background-subtracted data values (mean +/- SD) are graphed.

  • The concentrations of KIM-1 were measured in duplicates, interpolated from the KIM-1 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 25%, plasma (citrate) 25%, plasma (EDTA) 25%, plasma (heparin) 12.5%, and urine 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean KIM-1 concentration was determined to be 1,435 pg/mL in serum, 1,332 pg/mL in plasma (citrate), 1,444 pg/mL in plasma (EDTA), 1,726 pg/mL in plasma (heparin), and 2,005 pg/mL in urine.

  • The concentrations of KIM-1 were measured in duplicate and interpolated from the KIM-1 standard curve and corrected for sample dilution. Undiluted samples are as follows: RPMI media 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
