Human MOG-Ab ELISA Kit
FOR RESEARCH USE ONLY. Not for clinical diagnosis use
CATALOG #:18659
INTRODUCTION
? This kit allows for the determination of MOG-Abconcentrations in Human serum
? Detection of species: Human
? Detection medium: serum, cell culture supernates.
PRINCIPLE OF TEST
The kit assay Human MOG-Ab level in the sample,use Purified antigen to coat
microtiter plate wells, make solid-phase antigen, then add MOG-Ab to wells, Combined
antigen which With HRP labeled, become antigen – antibody- enzyme-antigen complex,
after washing Compley, Add TMB substrate solution,TMB substrate becomes blue
color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric
acid solution and the color change is measured spectrophotometrically at a wavelength
of 450 nm. The concentration of Human MOG-Ab in the samples is then determined by
comparing the O.D. of the samples to the standard curve.

STORAGE CONDITIONS
? The unopened kit shall be stored at [2-8 ℃] .
? For opened kit can be stored at [2-8 ℃] for up to 1 month. If not be used recently,
the standard should be kept in -20 ℃.
WASHING METHOD
? Manually washing method: shake away the remained liquid in the enzyme
plates; place some bibulous papers on the test-bed, and flap the plates on the
upside down strongly. Inject at least 0.35ml after-dilution washing solution into the
well, and marinate 1~2 minutes. Repeat this process according to your
requirements.
? Automatic washing method: if there is automatic washing machine, it should
only be used in the test when you are quite familiar with its function and
performance.

1. extract as soon as possible after Specimen collection,and according to the relevant
literature, and should be experiment as soon as possible after the extraction. If it
can’t, specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw
cycles.
2.Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
ASSAY PROCEDURE
1. Dilute and add sample:Dilute Original density Standard as follow table:
800pg/ml 5 Standard 150μl Original density Standard+150μl Standard diluent
400pg/ml 4 Standard 150μl 5 Standard+150μl Standard diluent
200pg/ml 3 Standard 150μl 4 Standard+150μl Standard diluent
100pg/ml 2 Standard 150μl 3 Standard +150μl Standard diluent
50pg/ml 1 Standard 150μl 2 Standard +150μl Standard diluent
2.add sample：Set blank wells separay (blank comparison wells don’t add sample and
HRP-Conjugate reagent, other each step operation is same). testing sample well. add
Sample dilution 40μl to testing sample well, then add testing sample 10μl (sample
final dilution is 5-fold), add sample to wells , don’t touch the well wall as far as
possible, and Gently mix.
3.Incubate: After closing plate with Closure plate membrane ,incubate for 30 min at
37℃.
4.Configurate liquid: 30-fold(or 20-fold) wash solution diluted 30-fold (or 20-fold) with
distilled water and reserve.

5.washing：Uncover Closure plate membrane, discard Liquid, dry by swing, add washing
buffer to every well, still for 30s then drain, repeat 5 times, dry by pat.
6.add enzyme：Add HRP-Conjugate reagent 50μl to each well, except blank well.
7.incubate：Operation with 3.
8.washing：Operation with 5.
9.color：Add Chromogen Solution A 50ul and Chromogen Solution B to each well, evade
the light preservation for 15 min at 37℃
10.Stop the reaction：Add Stop Solution50μl to each well, Stop the reaction(the blue
color change to yellow color).
11.assay：take blank well as zero , Read absorbance at 450nm after Adding Stop
Solution and within 15min.
CALCULATION OF RESULT
Take the standard density as the horizontal, the OD value for the vertical ,draw
the standard curve on graph paper, Find out the corresponding density according to the
sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate
the straight line regression equation of the standard curve with the standard density
and the OD value ,with the sample OD value in the equation, calculate the sample
density, multiplied by the dilution factor, the result is the sample actual density.
EXPIRATION
Six months [see label on the outer box for the specific date].

? The kit takes out from the refrigeration should be balanced 15-30 minutes in the
room temperature, if the coated ELISA plates have not been used up after opening,
the plate should be stored in sealed bag.
? washing buffer will Crystallization separation, it can be heated the water helps dissolve
when dilute . Washing does not affect the result.
? Pipette sample with pipettors each step, and proofread its accuracy frequently to
avoid the experimental error. Pipette sample within 5 min, if the number of sample
is big, recommend using multichannel pipettor.
? if the testing material content is excessively higher (The sample OD is bigger than
the first standard well ),please dilute Sample (n-fold), Please diluente and
multiplied by the dilution factor.（×n×5）
? Adhesive Strip only limits the disposable use to avoid cross-contamination.
? The substrate should evade the light to be preserved.
? Please refer to the user instruction strictly, the test result determination must take
the microtiter plate reader as a standard.
? The preparation of samples and all the reagents should refer to infective material
process.
? Do not mix reagents with those from other lots.
