Protein Quantification Products & Reviews

This product is a recombinant Human antibody that recognizes PDCD1. The antibody was expressed in mammalian cells with chemically defined culture media and was purified by affinity chromatography.

Recombinant Human Antibody (D25) is capable of binding to RSV, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti-RSV mAb and CH1-3 region of human IgG1 and a light chain (LC) encoding VL from anti-RSV mAb and CL of human kappa light chain. Exists as a disulfide linked dimer of the HC and LC hetero-dimer under non-reducing condition.

The antibody specifically targets the CD3 epsilon chain present on T lymphocytes. It binds to the CD3 molecule on the surface of T cells. By engaging with CD3, the mAb alters the immune response, offering potential in decelerating the progression of type 1 diabetes.

This product is a human monoclonal IgG1 kappan antibody targeting the Gnl domain of glycoprotein N (Gn) of severe fever with thrombocytopenia syndrome virus (SFTSV). This antibody shows the ability to neutralize SFTSV broadly, using the antibody neutralization of the SFTSV, which makes the antibody a specific drug and so clinically useful in preventing SFTSV through the treatment studies of diseases caused by infection.

Recombinant monoclonal antibody to Human VEGF is an angiogenesis inhibitor, a drug that slows the growth of new blood vessels. It is licensed to treat various cancers, including colorectal, lung, breast (outside the USA), glioblastoma (USA only), kidney, and ovarian. Bevacizumab is a humanized monoclonal antibody that inhibits angiogenesis by inhibiting vascular endothelial growth factor A (VEGF-A).

Recombinant monoclonal antibody to IL5RA. It is a monoclonal antibody for the treatment of asthma. It is directed against the alpha-chain of the interleukin-5 receptor (CD125).

Recombinant Mouse Antibody (M75) is capable of binding to CA9. The adhesion site of CA IX appears to overlap with the PGEEDLP epitope of the monoclonal antibody M75, since the antibody blocks attachment of cells to immobilized CA IX protein.

Recombinant monoclonal antibody to CD274. This antibody is a human IgG1 monoclonal antibody that targets and binds to PD-L1, a protein that is often overexpressed on the surface of cancer cells and immune cells in the tumor microenvironment.

Recombinant monoclonal antibody to Human IL5. It is a humanized monoclonal antibody that recognizes interleukin-5 (IL-5) and is used to treat certain kinds of asthma and white blood cell diseases. Recent studies have concluded that mepolizumab may improve exacerbations in patients with severe eosinophilic asthma, an adult-onset asthma that represents less than 5% of all asthma.

Recombinant monoclonal antibody to Human EGFR. Panitumumab (INN), formerly ABX-EGF, is a fully human monoclonal antibody specific to the epidermal growth factor receptor (also known as EGF receptor, EGFR, ErbB-1, and HER1 in humans).

This product is a recombinant Human antibody that recognizes MS4A1/CD20. The antibody was expressed in mammalian cells with chemically defined culture media and was purified by affinity chromatography.

This product is a recombinant Mouse antibody that recognizes DOTA. The antibody was expressed in mammalian cells with chemically defined culture media and was purified by affinity chromatography.

Recombinant Rabbit Antibody is capable of binding to Hypusine, expressed in Chinese Hamster Ovary cells (CHO).

Recombinant Human Antibody (B20-4) is capable of binding to VEGF, expressed in HEK293 cells. Expressed as the combination of a heavy chain (HC) containing VH from antiVEGF mAb and the CH1-3 region of human IgG1 and a light chain (LC) encoding VL from antiVEGF mAb and CL of human kappa light chain. Exists as a disulfide-linked dimer of the HC and LC heterodimer under non-reducing conditions.

Proteins purified from their natural, endogenous sources, preserving post-translational modifications and complex native structures for biologically relevant research applications.

A suite of analytical services, including SPR, BLI, and ITC, to quantitatively characterize the binding kinetics, affinity, and thermodynamics of biomolecular interactions.

Custom chemical conjugation of Polyethylene Glycol (PEG) polymers to proteins to enhance their pharmacokinetic properties, including increased half-life and reduced immunogenicity.
