Various Species ARG ELISA Kit, Lot 21AO-1041 [Cancer Immune Checkpoint Assay Kit]

The kit is designed for in vitro quantitative measurement of Various Species ARG in Plasma, Serum, Tissue Homogenate.

This immunoassay kit allows for the in vitro quantitative determination of general arginine,Arginine concentrations in serum, Plasma, tissue homogenates and Cell culture supernates and Other biological fluids.

ELISA

If samples generate values higher than the highest standard, further dilute the samples with the Sample Diluent and repeat the assay. Any variation in standard diluent, operator, pipetting technique, washing technique,incubation time or temperature, and kit age can cause variation in binding.

This assay recognizes recombinant and natural general Arginine. No significant cross-reactivity or interference was observed.

Limited by current skills and knowledge, it is impossible for us to complete the cross- reactivity detection between general Arginine and all the analogues, therefore, cross reaction may still exist.

Wash Buffer - If crystals have formed in the concentrate, warm to room temperature and mix gently until the crystals have completely dissolved. Dilute 30 mL of Wash Buffer Concentrate into deionized or distilled water to prepare 750 mL of Wash Buffer.
Standard - Reconstitute the Standard with 1.0 mL of Sample Diluent. This reconstitution produces a stock solution of 200 umol/L. Allow the standard to sit for a minimum of 15 minutes with gentle agitation prior to making serial dilution. The undiluted standard serves as the high standard (200 umol/L). The Sample Diluent serves as the zero standard (0 umol/L).

1.Add 100µL of standard or sample per well. Cover with the adhesive strip provided. Incubate for 2 hours at 37°C.
2.Remove the liquid of each well, don't wash.
3.Add 100µL of Biotin-antibody (1×) to each well. Cover with a new adhesive strip. Incubate for 1 hour at 37°C.
4.Aspirate each well and wash, repeating the process two times for a total of three washes.After the last wash, remove any remaining wash Buffer by aspirating or decanting. Invert the plate and blot it against clean paper towels.
5.Add 100µL of HRP-avidin (1×) to each well. Cover the microtiter plate with a new adhesive strip. Incubate for 1 hour at 37°C.
6.Repeat the aspiration/wash process for five times as in step 6.
7.Add 90µL of TMB Substrate to each well. Incubate for 20 minutes at 37°C. Protect from light.
8.Add 50µL of Stop Solution to each well, gently tap the plate to ensure thorough mixing.
9.Determine the optical density of each well within 5 minutes using a microplate reader set to 450nm.

Average the duplicate readings for each standard, control, and sample and subtract the average zero standard optical density. Create a standard curve by reducing the data using computer software capable of generating a four parameter logistic (4-PL) curve-fit.

The Stop Solution suggested for use with this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material.

The microtiter plate provided in this kit has been pre-coated with an antibody specific to Arginine. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for Arginine and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm.
