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 HA in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)  
1:20 Average % 87  
Range % 80-94  
1:40 Average % 92  
Range % 88-99  
1:80 Average % 97

Materials provided
  • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human HA antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
  • Two vials lyophilized standard --- Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
  • Biotin-labeled HA antibody(100 x concentrate) 1 x 120 μl ---Act as the detection antibody.
  • HRP-avidin (100 x concentrate) 1 x 120 μl --- Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
  • Biotin-antibody Diluent 1 x 15 ml ---Dilute the high concentration Biotin-antibody to an appropriate working solution.
  • HRP-avidin Diluent 1 x 15 ml ---Dilute the high concentration HRP-avidin solution to an appropriate solution.
  • Sample Diluent 1 x 50 ml---Dilute the sample to an appropriate concentration.
  • Wash Buffer (25 x concentrate) 1 x 20 ml --- Wash away unbound or free substances.
  • TMB Substrate 1 x 10 ml --- Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
  • Stop Solution 1 x 10 ml --- 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 that 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

Storage
Store at 2-8°C. Please refer to protocol.
Lead Time
3-5 working days after you place the order, and it takes another 3-5 days for delivery via DHL or FedEx

Q:

We are looking into the best method to distinguish HA manufactured by fermentation and nature human HA.

A:
Thanks for your inquiry.
CSB-E04805h Human Hyaluronic acid, HA ELISA Kit
This kit can detect nature HA in polymerized form. As for HA manufactured by fermentation, it usually exists in free form.
We think it can not be detected out by the kit.
