1.1X Phosphate Buffered Saline (PBS).
2.1% BSA PBS Solution (Dilution Buffer):For one plate dissolve 0.2 g of BSA in 20 ml of 1X PBS.
3.0.05% PBS-T Solution (Wash Buffer):For one plate dissolve 50µl of Tween 20 in 100mL of 1X PBS.
4.Detection Antibody:Reconstitute the lyophilised antibody with 0.55mL of distilled water. Gently mix the solution and wait until all the lyophilised material is back into solution.
5.Streptavidin - AP conjugate:For 1 plate dilute 10µl of Streptavidin-AP conjugate into 10 mL Dilution Buffer and mix well.

1.Add 25μl of 35% ethanol to every well.
2.Incubate plate at room temperature (RT) for 30 seconds.
3.Empty the wells by flicking the plate over a sink & gently tapping on absorbent paper. Thoroughly wash the plate 3x with 100μl of 1X PBS per well.
4.Add 100μl of diluted capture antibody to every well.
5.Cover the plate and incubate at 4°C overnight.
6.Empty the wells as previous and wash the plate once with 100μl of 1X PBS per well.
7.Add 100μl of culture media with 10% serum to every well.
8.Cover the plate and incubate at RT for 2 hours.
9.Empty the wells as previous and thoroughly wash once with 100μl of 1X PBS per well.
10.Add 100μl of sample, positive and negative controls cell suspension to appropriate wells providing the required concentration of cells and stimulant.
11.Cover the plate and incubate at 37°C in a CO2 incubator for an appropriate length of time (15-20 hours).
12.Empty the wells and remove excess solution then add 100μl of PBS-T to every well.
13.Incubate the plate at 4°C for 10 min.
14.Empty the wells as previous and wash the plate 3x with 100μl of PBS-T.
15.Add 100μl of diluted detection antibody to every well.
16.Cover the plate and incubate at RT for 1 hour 30 min.
17.Empty the wells as previous and wash the plate 3x with 100μl of PBS-T.
18.Add 100μl of diluted Streptavidin-AP conjugate to every well.
19.Cover the plate and incubate at RT.
20.Empty the wells and wash the plate 3x with 100μl of PBS-T.
21.Peel of the plate bottom and wash both sides of the membrane 3x under running distilled water, once washing complete remove any excess solution by repeated tapping on absorbent paper.
22.Add 100μl of ready-to-use BCIP/NBT buffer to every well.
23.Incubate the plate for 5-15 min monitoring spot formation visually throughout the incubation period to assess sufficient colour development.
24.Empty the wells and rinse both sides of the membrane 3x under running distilled water. Completely remove any excess solution by gentle repeated tapping on absorbent paper.

1.For research use only not to be used as a diagnostic test.
2.Do not eat, drink, smoke or apply cosmetics where kit reagents are used.
3.Cover or cap all reagents when not in use.
4.Do not mix or interchange reagents between different lots.
5.Do not use reagents beyond the expiration date of the kit.
6.When pipetting reagents, maintain a consistent order of addition from well-to-well. This will ensure equal incubation times for all wells.
7.BCIP/NBT buffer is potentially carcinogenic and should be disposed of appropriately, caution should be taken when handling this reagent, always wear gloves.

1.Handling of reagents, serum or plasma specimens should be in accordance with local safety procedures.
2.When not in use, kit components should be stored refrigerated or frozen as indicated on vials or bottles labels.
3.All reagents should be warmed to room temperature before use.
4.Use a clean disposable plastic pipette tip for each reagent, standard, or specimen addition in order to avoid cross contamination.
5.Use a clean plastic container to prepare the washing solution.
6.Thoroughly mix the reagents and samples before use by agitation or swirling.

Store kit reagents between 2 and 8°C.

Immediately after use remaining reagents should be returned to cold storage (2 to 8°C). The expiry of the kit components can only be guaranteed if the components are stored properly, and if in the case of repeated use of one component, the reagent is not contaminated by the first handling.

Expiry of the kit and reagents is stated on box front labels.

Select online data sheet information is drawn from bioinformatics databases, occasionally resulting in ambiguous or non-relevant product information. It is the responsibility of the customer to review, verify, and evaluate the information to make sure it matches their requirements before purchasing the kit. Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved.

IFNG2

This gene encodes a soluble cytokine that is a member of the type II interferon class. The encoded protein is secreted by cells of the both the innate and adaptive immune systems. The active protein is a homodimer that binds to the interferon gamma receptor which triggers a cellular response to viral and microbial inflections. Mutations in this gene are associated with an increased susceptibility to viral, bacterial and parasitic infections and to several autoimmune diseases.
