R-L-147	Recombinant Peptostreptococcu s magnus Protein L	Protein L, derived from Streptococcus Alimentarius, is a protein that can bind to a wide range of immunoglobulins. It only binds to the antibody kappa light chain without affecting the antibody antigen binding site. Compared to Protein A or Protein G, Protein L can bind antibodies from various sources and subclasses more broadly. It does not bind immunoglobulins from cattle, goats or sheep, and can be used to purify monoclonal antibodies from culture medium supplemented with BSA or FCS.	price>
R-L-148	Recombinant Human Vascular Endothelia	Vascular Endothelial Growth Factor is a potent growth and angiogenic cytokine. It stimulates proliferation and survival of endothelial cells. VEGF-A is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor. There are multiple isoforms of VEGF-A that result from alternative splicing of mRNA from a single, 8-exon VEGFA gene, with VEGF-165 being the most abundant. The VEGF-165 isoform is a secreted protein that acts on receptors VEGFR-1 and VEGFR-2 to modulate endothelial cell proliferation and angiogenesis.	price>
R-L-149	Recombinant Human Fibroblast Growth Factor	Fibroblast growth factor-basic (bFGF), also known as FGF-2, is a heparin-binding member of the FGF superfamily. It plays an important role in cell proliferation and differentiation associated with embryogenesis, tissue regeneration, wound healing, CNS development, angiogenesis, and tumor progression.	price>
R-R-0149	Capsaicin-BSA	Capsaicin bovine serum albumin/Capsaicin-BSA refers to a conjugate formed by binding capsaicin, the active compound found in chili peppers, to bovine serum albumin (BSA), which is a widely used protein carrier. This conjugation is often performed to enhance the solubility, stability, and bioavailability of capsaicin.The capsaicin-BSA conjugate is commonly used in research and pharmaceutical applications, such as studying the delivery of capsaicin, assessing its interactions with biological systems, and evaluating its therapeutic potential in treating various conditions, including pain and inflammation.	price>
R-L-151	Recombinant Human Manganese Superoxide Dismutase	Superoxide dismutase 2 (SOD2)/manganese SOD (Mn-SOD) is an antioxidant enzyme that protects cells from oxidative stress by scavenging superoxide anions.It exists as a homotetramer where each monomer is composed of an N-terminal α-hairpin domain and a C-terminal α/β domain that contain Mn-binding catalytic active sites.	price>
R-L-155	Streptavidin-HRP	Streptavidin-HRP conjugate is typically used in the immunodetection of biotinylated proteins. This conjugate is suitable for use in immunoblotting, ELISA, immunomicroscopy. The amount of conjugate provided is sufficient for 25 western blots using 10 ml of working solution per reaction or 25 immunostaining reactions using 1 ml of working solution per reaction as appropriate.	price>
R-L-156	Recombinant Bovine(rb-EK)	Enterokinase is a serine proteolytic enzyme, which can recognize the sequence of ASP ASP Lys (ddddk) in the protein efficiently and specifically, hydrolyze the peptide bond at the C-terminal of lysine (Lys , K), produce cleavage, hydrolyze trypsinogen to trypsin in the organism. Because enterokinase has high specificity and efficient enzymatic cleavage, it is widely used in genetic engineering. Activity definition: 25 ℃, reaction buffer 50 mM Tris-HCl (pH 8.0), substrate 50 μ G 1 mg/ml of fusion protein containing restriction site, the amount of enzyme required to cut 95% of fusion protein within 16 hours is 1 enzyme activity unit (1 U).	price>
R-L-157	Recombinant Bovine,rbEK-His	Enterokinase (EC 3.4.21.9) is a serine proteolytic enzyme, which can recognize the sequence of ASP ASP Lys (DDDDK) in protein efficiently and specifically, hydrolyzed peptide binding at the c-terminal of lysine (Lys, K), producing cleavage, hydrolyzes trypsinogen into trypsin in the body. Because enterokinase has high specificity and efficient enzymatic cleavage, it is widely used in genetic engineering. Product development. Natural enterokinase consists of a heavy chain of 115kda and a light chain of 35kDa. The heavy chain anchors the cell membrane, and the light chain has full enzymatic catalytic activity. The central region of light chain activity (235A. A., 26.2kda) secreted and expressed by E. coli is more active than that of bovine enterokinase, which is particularly suitable for the enzymatic digestion of the fusion protein of genetic engineering. Activity definition: 25 ℃, reaction buffer 50 mM Tris-HCl (pH 8.0), substrate 50 μ G 1 mg/ml of fusion protein containing restriction site, the amount of enzyme required to cut 95% of fusion protein within 16 hours is 1 enzyme activity unit (1 U).	price>
R-L-158	Recombinant Core Streptavidin,r-cSA	Compared to native streptavidin, rc-SA is improved in stability and solubility by removing the sequence unrelated to activity. In addition, a cysteine residue is inserted at the C-terminus of rc-SA for covalent conjugation to the resin.	price>
R-L-159	Recombinant Core Streptavidin 2,r-csa2	Compared to native streptavidin, r-cSA2 is improved in stability and solubility by removal of the activity-unrelated sequence. Compared to r-csa, the amino acid sequence of this product does not contain cysteine, so it does not need reduction therapy.	price>
