	LGP2 Protein, Human (HEK293, FLAG) CGAS; Probable ATP-dependent RNA helicase DHX58; Probable ATP-dependent helicase LGP2; Protein D11Lgp2 homolog; RIG-I-like receptor 3; RLR-3; RIG-I-like receptor LGP2; RLR	Human	HEK293
	LGP2 protein is a key regulator of RIGI- and IFIH1/MDA5-mediated antiviral signaling and has dual negative and positive functions affected by factors such as infected viruses and target cells. LGP2 lacks a CARD domain for independent initiation of antiviral signaling and therefore inhibits RIG-I through multiple mechanisms, including competition for RNA binding and obstruction of interaction with MAVS/IPS1. LGP2 Protein, Human (HEK293, FLAG) is the recombinant human-derived LGP2 protein, expressed by HEK293 , with C-Flag labeled tag.

2'-Deoxy-2'-fluorouridine-d2

2'-Deoxy-2'-fluorouridine-d₂ is the deuterium labeled 2'-Deoxy-2'-fluorouridine . 2'-Deoxy-2'-fluorouridine is a derivative of the pyrimidine nucleoside uridine. 2'-Deoxy-2'-fluorouridine is a nucleoside analog that inhibits the replication of wild-type viruses by binding to the viral RNA. Hepatitis C polyU/UC RNA strands containing 2'-Deoxy-2'-fluorouridine, bind to RIG-I but do not activate RIG-I signaling in a reporter assay using Huh7 cells. 2'-Deoxy-2'-fluorouridine also has been used as a starting material in the synthesis of respiratory syncytial virus (RSV) polymerase inhibitors. 2'-Deoxy-2'-fluorouridine can incorporate into DNA and RNA in rat and woodchuck model upon administration. 2'-Deoxy-2'-fluorouridine can be studied in anti-viral research .

ssRNA40 sodium R-1075 sodium		CpG ODNs
ssRNA40 sodium (R-1075 sodium) is a single-stranded RNA40 derived from HIV-1. ssRNA40 sodium activates the TLR7, TLR8, TLR2, *RIG-I, MDA5, MyD88, Caspase-3, IRE1α, NLRP3* inflammasome and IRF7 signaling pathways. ssRNA40 sodium alters mRNA expression in neutrophils, induces pro-inflammatory cytokines, ROS, autophagy (autophagy), pyroptosis (pyroptosis), neuronal death, neurodegeneration, aggregate formation and NK cell activation. ssRNA40 sodium activates the expression of CD62L, CD11b, CD69, MX1, OAS1, ATG7, LC3B and XBP1 in immune cell and neuronal populations. ssRNA40 sodium causes cortical neuron loss and axonal damage in mice in a TLR7-dependent manner. ssRNA40 sodium can be used in research on HIV-1 infection, neurodegeneration, COVID-19 and HIV-associated neurological disorders .
