 Specificity    This assay has high sensitivity and excellent specificity for detection of human FSTL4. No significant cross-reactivity or interference between human FSTL4 and analogues was observed.
Section Bar
 Samples    Serum, plasma, tissue homogenates
 Assay Type    Sandwich
 Detection Range    1.56 ng/ml-100 ng/ml.
 Sensitivity    The minimum detectable dose of human FSTL4 is typically less than 0.39 ng/ml. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined the mean O.D value of 20 replicates of the zero standard added by their three standard deviations.
 Intra-assay Precision    Intra-assay Precision (Precision within an assay): CV%<8%. Three samples of known concentration were tested twenty times on one plate to assess.
 Inter-assay Precision    Inter-assay Precision (Precision between assays): CV%<10%. Three samples of known concentration were tested in twenty assays to assess.

 Preparation and Storage    Unopened test kits should be stored at 2 to 8 degree C upon receipt. Please refer to pdf manual for further storage instructions.
 ISO Certification    Manufactured in an ISO 9001:2008 Certified Laboratory.
 Product Note    Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.
 Other Notes    Small volumes of FSTL4 elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
 Searchable Terms for FSTL4 purchase    MBS920045 is a ready-to-use microwell, strip plate Sandwich ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the follistatin-like 4 (FSTL4) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range of 1.56 ng/ml-100 ng/ml in biological research samples containing FSTL4, with an estimated sensitivity of The minimum detectable dose of human FSTL4 is typically less than 0.39 ng/ml. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined the mean O.D value of 20 replicates of the zero standard added by their three standard deviations. The ELISA analytical biochemical technique of the MBS920045 kit is based on FSTL4 antibody-FSTL4 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect FSTL4 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, FSTL4. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions such as Serum, plasma, tissue homogenates. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Related Product Information for FSTL4 elisa kit

Principle of the assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for FSTL4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any FSTL4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for FSTL4 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of FSTL4 bound in the initial step. The color development is stopped and the intensity of the color is measured.
