      Intended use

      This ELISA kit applies to the in vitro quantitative determination of Human MBP concentrations in serum, plasma and other biological fluids.

      Test principle

      This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human MBP. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human MBP and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human MBP, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human MBP. You can calculate the concentration of Human MBP in the samples by comparing the OD of the samples to the standard curve.

      Specificity

      This kit recognizes Human MBP in samples. No significant cross-reactivity or interference between Human MBP and analogues was observed.

      Typical data

      As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

      Precision

      Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human MBP were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human MBP were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Human MBP spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

      Sample Type Range (%) Average Recovery (%)
      Serum (n=5) 87-101 93
      EDTA plasma (n=5) 90-103 95
      Cell culture media (n=5) 88-99 94

      Linearity

      Samples were spiked with high concentrations of Human MBP and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.

      Asked: If I received the MBP kit, where should I store it, and how long? What does the expiration mean? When I open the kit, Can I use the Standard and reagent one more time?

      Answered: Thank you for your message. Generally, an unopened kit can be stored at 4℃ for 1 month. If the kit is not used within 1 month, pls store the below items separately according to the following conditions once the kit is received. 1. Micro ELISA Plate(Dismountable), Reference Standard, Concentrated Biotinylated Detection Ab (100×) ,pls store at -20℃; 2. Concentrated HRP Conjugate (100×), pls store at -20℃(shading light); 3. For the below reagents, pls store at 4℃; Reference Standard & Sample Diluent; Biotinylated Detection Ab Diluent; HRP Conjugate Diluent; Concentrated Wash Buffer (25×); Substrate Reagent; Stop Solution; The expiration means the shelf life, which is 6 months. For the Standard and reagent, the diluted reagents are not recommended repetitive use. You'd better prepare before use. Any other questions, pls feel free to send it to us (techsupport@elabscience.com). All the best.
