Ovine IL-21 ELISA Kit

RayBio® Ovine (sheep) IL-21 ELISA Kit.

Product Description

Specifications

Size	1 Plate Kit, 2 Plate Kit, 5 Plate Kit
Estimated Lead Time	4-7 weeks
Species	Ovine (sheep)
Accession Number	H6SGV5
Gene Id	100862657
Gene Symbols	IL21
Protein Name / Synonyms	Interleukin
Quantitative/Semi-Quantitative	Quantitative
Solid Support	96-well Microplate
Design Principle	Sandwich-based
Method Of Detection	Colorimetric
Research Area	Inflammation
Shipping Type	Blue ice
Storage	≤-20°C
Note	This ELISA uses an antibody pair and standard that have been validated for multiplex array products, but not for the 96-well plate ELISA format. Thus, this ELISA requires a 4 - 7 week development phase, which RayBiotech begins after receiving an order for the kit. After development, the kit will have passed RayBiotech's ELISA quality control tests, and will thereafter have a typical 1 - 2 day lead time for orders placed.

Protocol Outline

Prepare all reagents, samples and standards as instructed in the manual.
Add 100 µl of standard or sample to each well.
Incubate 2.5 h at RT or O/N at 4°C.
Add 100 µl of prepared biotin antibody to each well.
Incubate 1 h at RT.
Add 100 µl of prepared Streptavidin solution to each well.
Incubate 45 min at RT.
Add 100 µl of TMB One-Step Substrate Reagent to each well.
Incubate 30 min at RT.
Add 50 µl of Stop Solution to each well.
Read at 450 nm immediately.

Storage/Stability

The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.

Customize This Ovine IL-21 ELISA

We manufacture our ELISAs in-house, so we can build a custom version for your study.

Post-translational modifications (PTMs): Detect modified IL-21 (IL21), including phosphorylation, acetylation, S-nitrosylation, S-acylation, oxidation, lactylation, sumoylation, ubiquitination, nitration, carbamylation, and more
Sample types: Validation in your matrix using samples you provide, such as CSF, urine, saliva, lysates, or exosomes
Also available: More sensitive platforms such as Simoa^® and NexaTag^®, multiplex panels, bulk lots, and other species when suitable reagents exist

Feasibility varies by target and modification, and we’ll tell you upfront what’s achievable.
