The Bosterbio OneStep Human PSA Pre-Coated ELISA (Enzyme-Linked Immunosorbent Assay) kit is a solid phase immunoassay specially designed to measure Human PSA with a 96-well strip plate that is pre-coated with antibody specific for PSA. The detection antibody is a HRP conjugated antibody specific for PSA. The capture antibody is monoclonal antibody from mouse, and the detection antibody is monoclonal antibody from mouse. The kit is analytically validated with ready to use reagents. To measure Human PSA, add standards and samples to the wells, then add the HRP conjugated detection antibody. Wash away the unbounded protein and HRP conjugated detection antibody. TMB is substrate to HRP and will be catalyzed to produce a blue color product, which changes into yellow after adding acidic stop solution. Upon addition of the substrate, the density of the yellow product is linearly propotional to Human PSA in the sample. Read the density of the yellow product in each well using a plate reader, and benchmark the sample wells' readings against the standard curve to determine the concentration of Human PSA in the sample.

Product Name | Human Prostate Specific Antigen (PSA) ELISA Kit |
---|---|
SKU/Catalog Number | EK7080 |
Description | Sandwich High Sensitivity ELISA kit for Quantitative Detection of Human PSA. 96wells/kit, with removable strips. |
Cite This Product | Human Prostate Specific Antigen (PSA) OneStep ELISA Kit (Boster Biological Technology, Pleasanton CA, USA, Catalog # EK7080) |
Validated Species | Human |
Application | ELISA *Our Boster Guarantee covers the use of this product in the above tested applications. **For positive and negative control design, consult "Tissue specificity" under Protein Target Info. |
Cross Reactivity | There is no detectable cross-reactivity. |
Pack Size | 96wells/kit, with removable strips. |
Sensitivity | 0.5 ng/ml *Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive. |
---|---|
Assay Range | 1-32 ng/ml *This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range. |
Sample Type | Serum *The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine? ELISA kit should detect it. **For protocol and tips regarding preparing your sample of interest, please check our ELISA sample preparation guide. |
Storage | Store the kit at 2°C to 8°C. Keep microwells sealed in a dry bag with desiccants. The reagents are stable until expiration of the kit. Do not expose reagent to heat, sun, or strong light. Avoid multiple freeze-thaw cycles(Shipped with wet ice.) |
