Background Information
cGAS (Cyclic GMP-AMP synthase), also known as C6orf150 or h-cGAS, is a 522 aa protein. cGAS mediates innate immune responses against invading pathogens, or against self-dsDNA, which causes autoimmune disorders. The cGAS sensor not only recognizes cytosolic dsDNA but also synthesizes the second messenger cGAMP from ATP and GTP, which then binds to and activates STING. STING undergoes conformational changes and translocation from the endoplasmic reticulum to the Golgi apparatus to encounter TBK1 and IRF3, eventually triggering the production of type I IFNs.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive forproviding their feedback.
FH Hannah (Verified Customer) (12-10-2024) | Detects authentic cGAS band ~58kDa by western blot that disappears upon knockdown, but also detects a non-specific band just above, ~60kDa, which is not ideal for figure generation and concerning for other applications such as IF.
 |
FH Sonia (Verified Customer) (09-12-2023) | Very clear staining of ruptured micronuclei in U2OS cells, fixed in 4% FA and permeabilised with PBS-Triton 0.5%. Primary antibody incubation was performed o/n at 4ºC in blocking buffer at 1:250.
|
FH Shunbin (Verified Customer) (06-15-2023) | Produces a specific band and two other non-specific bands under the indicated conditions. The other cGAS Ab from Cell Signaling Technology produces one single band. (compare images attached
 |
FH Zhiping (Verified Customer) (03-18-2022) | Good Ab for WB
|
FH Coralie (Verified Customer) (10-20-2021) | Cytosolic staining of cGAS (forms dots, after PFA fixation).
