Inter-assay Precision (Precision between assays)
3 samples with low, middle and high level Virus Induced Signaling Adapter (VISA) were tested on 3 different plates, 8 replicates in each plate.
CV(%) =
SD/meanX100
Intra-Assay
CV<10%

Preparation and Storage
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Related Product Information for VISA elisa kit
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Virus Induced Signaling Adapter (VISA). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Virus Induced Signaling Adapter (VISA). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Virus Induced Signaling Adapter (VISA), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Virus Induced Signaling Adapter (VISA) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

NCBI Description

This gene encodes an intermediary protein necessary in the virus-triggered beta interferon signaling pathways. It is required for activation of transcription factors which regulate expression of beta interferon and contributes to antiviral immunity. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

Uniprot Description

MAVS: Required for innate immune defense against viruses. Acts downstream of DDX58/RIG-I and IFIH1/MDA5, which detect intracellular dsRNA produced during viral replication, to coordinate pathways leading to the activation of NF-kappa-B, IRF3 and IRF7, and to the subsequent induction of antiviral cytokines such as IFN-beta and RANTES (CCL5). May activate the same pathways following detection of extracellular dsRNA by TLR3. May protect cells from apoptosis. Interacts with DDX58/RIG-I, IFIH1/MDA5, TRAF2 and TRAF6. May interact with IRF3, FADD, RIPK1, CHUK and IKBKB. Does not interact with TBK1. Interacts with and is cleaved by HCV and hepatitis GB virus B NS3/4A proteases. Interacts with and is cleaved by HHAV protein 3ABC. Interacts with NLRX1. Interaction with NLRX1 requires the CARD domain. Interacts with PSMA7. Interacts with TRAFD1. Interacts (via C-terminus) with PCBP2 in a complex containing MAVS/IPS1, PCBP2 and ITCH. Interacts with CYLD. Interacts with SRC. Interacts with DHX58/LGP2 and IKBKE. Present in T-cells, monocytes, epithelial cells and hepatocytes. Ubiquitously expressed, with highest levels in heart, skeletal muscle, liver, placenta and peripheral blood leukocytes. 3 isoforms of the human protein are produced by alternative splicing.

Product Notes

The Human VISA mavs (Catalog #AAA2019789) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA2019789 ELISA Kit recognizes Human VISA. It is sometimes possible for the material contained within the vial of "Virus Induced Signaling Adapter (VISA), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
