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.).
Wheat germ agglutinin-AF488 (WGA-AF488) is a cell membrane-specific staining agent prepared by conjugating wheat germ agglutinin with the Alexa Fluor 488 (HY-D1304) fluorescent dye, and it binds to cell surface glycoproteins with high affinity. Wheat germ agglutinin-AF488 is applied in fluorescence microscopy and confocal imaging techniques, and it can clearly label the membrane structures of various cells including breast cancer cells, enabling high-resolution visual observation. Wheat germ agglutinin-AF488 is used in studies of breast cancer and triple-negative breast cancer to observe cell morphology and membrane dynamic changes.
Hemocyanin is an extracellular giant copper-containing glycoprotein. Hemocyanin can be found in the hemolymph of both mollusk and arthropod. Hemocyanin is responsible for oxygen transport. Hemocyanin is also involved in several physiological processes, such as energy storage, osmoregulation, molt cycle and exoskeleton formation. Hemocyanin in shrimp can enhance its immune response by modulating the p38 MAPK pathway. Hemocyanin from Penaeus monodon could act as an antiviral agent against a variety of viruses including DNA and RNA viruses. Hemocyanin from horseshoe crab Carcinoscorpius rotundicauda could possess a strong antimicrobial defense by the production of ROS activated with microbial proteases. Hemocyanin from L. vannamei would be effective against cervical cancer cell growth.
Fibronectin, bovine plasma is a fibronectin derived from bovine plasma. Fibronectin is an extracellular matrix protein that is upregulated and essential in many developmental processes, and also exists in the pathological progression of tissues and wound healing. Fibronectin specifically binds to a large number of molecules, including other components of the extracellular matrix, signaling molecules and cell adhesion molecules. The interaction between cells and fibronectin leads to bidirectional crosstalk, which regulates cell functions and induces cell-dependent changes in the extracellular matrix. Fibronectin, bovine plasma inhibits the production of bovine leukemia virus (BLV) p24 core protein in naturally infected bovine peripheral blood mononuclear cells.
