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 (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
             
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of human Aβ1-42 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Materials provided
  • A micro ELISA plate --- The 96-well plate has been pre-coated with anti-human Aβ1-42 antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
  • Two vials lyophilized standard --- Dilute a bottle of standard at dilution series, read the OD values, and then draw a standard curve.
  • One vial Biotin-labeled Aβ1-42 antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
  • One vial HRP-avidin (100 x concentrate) (120 μl/bottle) --- Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
  • One vial Biotin-antibody Diluent (15 ml/bottle) ---Dilute the high concentration Biotin-antibody to an appropriate working solution.
  • One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the high concentration HRP-avidin solution to an appropriate solution.
  • One vial Sample Diluent (50 ml/bottle)---Dilute the sample to an appropriate concentration.
  • One vial Wash Buffer (25 x concentrate) (20 ml/bottle) --- Wash away unbound or free substances.
  • One vial TMB Substrate (10 ml/bottle) --- Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
  • One vial Stop Solution (10 ml/bottle) --- Stop the color reaction. The solution color immediately turns from blue to yellow.
  • Four Adhesive Strips (For 96 wells) --- Cover the microplate when incubation.
  • An instruction manual
Materials not provided
  • A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at 540 nm or 570 nm.
  • An incubator can provide stable incubation conditions up to 37°C±5°C.
  • Centrifuge
  • Vortex
  • Squirt bottle, manifold dispenser, or automated microplate washer
  • Absorbent paper for blotting the microtiter plate
  • 50-300ul multi-channel micropipette
  • Pipette tips
  • Single-channel micropipette with different ranges
  • 100ml and 500ml graduated cylinders
  • Deionized or distilled water
  • Timer
  • Test tubes for dilution

Sample type: Tissue homogenate(Brain tissues)

Sample species: Human

Review: The discrimination index in the object recognition test. After the MWM test and the object recognition test, animals were sacrificed and the brain tissues were collected. Aβ42 levels in the cortex (K) and hippocampus (L) were detected by ELISA. # p < 0.05, ###p < 0.001 vs. Wt group. * p < 0.05, **p < 0.01, ***p < 0.001 vs. APP/PS1 group.
