Kit contents scale proportionally with size, except sealing tape.
Example: The V1 kit contains 5X the listed quantities above, but will exclude the sealing tape.

For the “C” and “V” kits, the supplied 96-well strip plate consists of twelve 8-well strips in a support frame. This enables custom plate configurations.

Description

The FastScanTM Total cGAS ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of cGAS. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with cGAS in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of cGAS.

*Antibodies in this kit are custom formulations specific to kit.

Specificity/Sensitivity

The FastScan™ Total cGAS ELISA Kit detects endogenous levels of cGAS as shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background

Cyclic GMP-AMP synthase (cGAS, MB21D1) is an antiviral enzyme that produces the second messenger cyclic-GMP-AMP (cGAMP) in response to cytoplasmic DNA (1,2). The cGAS protein acts as a cytosolic DNA sensor that binds DNA and produces the cGAMP second messenger from ATP and GTP (1,2). cGAMP binds to and activates STING, a transmembrane adaptor protein that is a critical component of the cellular innate immune response to pathogenic cytoplasmic DNA (1-4). STING is ubiquitously expressed and found predominantly in the ER (3). Following activation, STING translocates with TBK1 to perinuclear endosomes (5). The TBK1 kinase phosphorylates and activates interferon regulatory factors (IRFs) and NF-κB, which leads to the induction of type I interferon and other immune response genes (3-5).

Figure 1. cGAS protein is expressed in MDA-MB-435S cells but absent in SNB-19 cells. The relationship between lysate protein concentration from MDA-MB-435S and SNB-19 cells and the absorbance at 450 nm using the FastScan™ Total cGAS ELISA Kit #91304 is shown in the upper figure. The corresponding western blot using cGAS antibody is shown in the lower figure. Unstarved MDA-MB-435S or SNB-19 cells were harvested and then lysed.
