Target:  

Akt TGF-β Receptor

Phosphatidylserine (Phospholipids) is a well-conserved anti-inflammatory and immunosuppressive signal. Phosphatidylserine is involved in membrane translocation and the activation of protein kinase C, participating in Akt signaling through its interaction with PIP3. The local exposure of Phosphatidylserine can interact with complement and other proteins, promoting microglial phagocytosis during critical periods of synaptic refinement. Phosphatidylserine can promote blood coagulation in the extracellular environment and acts as a "eat me" signal to clear out apoptotic cells. Phosphatidylserine can suppress inflammation in tissues by inducing TGF-β secretion and inhibiting immune responses .

Synonyms: LPS, from bacterial (Klebsiella pneumoniae)
Lipopolysaccharides, from Klebsiella pneumoniae (LPS, from bacterial (Klebsiella pneumoniae)) are lipopolysaccharide endotoxins and TLR4 activators derived from Klebsiella pneumoniae, and are classified as S-type LPS. Lipopolysaccharides, from Klebsiella pneumoniae exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from Klebsiella pneumoniae may participate in bacterial immune evasion by inhibiting complement-mediated killing and suppressing the host's secretion of antimicrobial peptides, thereby allowing the bacteria to escape immune defenses. Lipopolysaccharides, from Klebsiella pneumoniae possess high viscosity and resistance to serum-mediated killing, which may lead to sepsis. Lipopolysaccharides, from Klebsiella pneumoniae can be used to construct Acute Lung Injury Model .
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.

Synonyms: CVF
Cobra Venom Factor (CVF) is a selective activator targeting complement components C3, C5, and factor B in the complement system. After binding to factor B, Cobra Venom Factor is cleaved by factor D, forming a stable C3/C5 convertase resistant to regulatory proteins H and I. This continuously hydrolyzes C3 and C5, depleting serum complement while inducing neutrophil migration, vascular leakage, and increased TNF-α levels. Cobra Venom Factor can be used to deplete complement and mimic complement activation-related pathological states, and is applied in animal models of complement-mediated diseases such as acute respiratory distress syndrome (ARDS), sepsis, and shock. Cobra Venom Factor can be isolated from the venom of cobras (e.g., Naja atra, Naja melanoleuca, Naja kaouthia, etc.) .

Purity:  ≥98.0%
Synonyms: N-Acetyl-L-serine
N-Acetylserine (N-Acetyl-L-serine) is a complement pathway modulator targeting activated third complement protein (C3b) and an amino-terminal residue (an N-terminal acetylation modification group). N-Acetylserine reacts with the exposed thioester group of C3b via its hydroxyl group, thereby blocking the covalent binding of glycerol to this thioester group. N-Acetylserine widely exists in soluble proteins of mammalian cells (accounting for approximately 80% of such proteins). N-Acetylserine has a blocking property that prevents direct Edman sequencing of proteins; deblocking is achievable through trifluoroacetic acid-catalyzed N→O acetyl migration followed by β-elimination. N-Acetylserine is suitable for sequencing of proteins with N-terminal acetylserine modification .

Mucinase StcE is a zinc metalloproteinase belonging to the M66 family, which is secreted by enterohemorrhagic Escherichia coli via the type II general secretion pathway. Mucinase StcE specifically recognizes and cleaves the 'T*XT' motif in mucin-type glycoproteins with α-O-glycans (such as MUC2, Mucin 7, Glycoprotein 340, CD45, CD43, C1 Esterase Inhibitor (HY-P991629), etc.). By degrading the mucus layer to reduce its viscosity, inhibiting complement cascade activation, and localizing complement regulatory factors to the cell membrane, Mucinase StcE helps bacteria penetrate the mucosal barrier, adhere to host cells, and evade immune clearance. Mucinase StcE can serve as a mucin-specific proteolytic tool for research on mucinous carcinomas derived from the colon, esophagus, and salivary glands .
