Sensitivity 1.25 μg/mL
Assay Time 1-5h
Sample Volume 50-100ul
Detection Wavelength 450 nm
Research Area Immunology
Assay Principle quantitative
Measurement Competitive
Intra-assay Precision (Precision within an assay): CV%<15%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<15%      
Three samples of known concentration were tested in twenty assays to assess.    
To assess the linearity of the assay, samples were spiked with high concentrations of fish IgM 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)  
1:1 Average % 93  
Range % 86-101  
1:2 Average % 97  
Range % 90-104  
1:4 Average % 95  
Range % 84-105  
1:8 Average % 95  
Range % 91-99  
The recovery of fish IgM spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Materials provided
  • A 96-well Assay plate --The 96-well plate has been pre-coated with goat-anti-rabbit antibody.
  • Standard (6 x 0.5 ml) --Dilute the standard at dilution series, read the OD values, and then draw a standard curve.
  • HRP-conjugated IgM (1 x 6 ml) --Bind to the IgM antibody, and HRP catalyzes the TMB to elicit a chromogenic reaction.
  • IgM Antibody (1 x 6 ml) --Interact with the IgM.
  • Sample Diluent (2 x 20 ml) --Reconstitute the standard and dilute the sample to an appropriate concentration.
  • Wash Buffer (25x concentrate) (1 x 20 ml) --Wash away unbound or free substances.
  • TMB Substrate (1x 10 ml) --Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
  • Stop Solution (1 x 10ml) --Stop the color reaction. The solution color immediately turns from blue to yellow.
  • Four Adhesive Strips (For 96 wells)
  • An Instruction manual
Materials not provided
  • A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at 600 nm - 630 nm.
  • An incubator that can provide stable incubation conditions up to 37°C±5°
  • 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

CUSABIO fish immnoglobulin M (IgM) ELISA kit Does this kit can be used for separate experiments?around 30-40 wells every time?

Thanks for your inquiry.
#CSB-E12045Fh,Fish immunoglobulin M (IgM) ELISA Kit
YES,it can.The plate is Breakapart and can be used for seperate experiments.You can put the break part in the
Aluminum foil bag for next use.The manual is provided to you by e-mail.Additionally,we received 21 published papers until now.You can refer to it. Pls let me know if you have any further questions. Thank you.

Regarding your ELISA kit CSB-E12045Fh, could you please advise on the following:
1. Capture Antibody: host animal species, clonality
2. Detection Antibody: host animal species, clonality
3. Standard
Also, what sample types have been tested with this kit, and what were the reference values?

Thanks for your inquiry.
The target is a special protein and there is no uniprot.
This kit is based on competitive method. The plate is coated with goat-anti-rabbit antibody. The specific antibody is rabbit polyclonal antibody. The standard is purified crude extract of natural samples.
We tested undiluted serum and plasma before and the test value is 1.25--3.75μg/ml.
Pls let me know if you have any further questions. Thank you.
