Diagnostic antibodies and antigens for lung diseases testing: ACE2/hFc, ACE2/his

Full List Download Lung disease such as asthma, COPD, infections like influenza, pneumonia and tuberculosis and lung cancer can affect respiratory function, or the ability to breathe, and pulmonary function. some of the lung diseases are caused by bacterial, viral, or fungal infections and some other lung diseases are associated with environmental factors, including asthma, […]

Diagnostic antibodies and antigens for cancer detection – TG, CA-125, SCC Ag, PIVKA-Ⅱ, ProGRP, Calcitonin, NSE, CA-724, HE4, CA15-3, FER, CYFRA21-1, HER2, HSP90α, S100B, CEA, AFP, sFlt-1, PSA, hEGF, TFF2, TFF3, CA199, CA50, TK1

Regardless of the advances in the cancer therapy, delayed symptoms and lack of successful diagnosis of cancer at early stage increased the death rate. Tumor-associated antigens (TAAs) and their antibodies have been identified as potential markers in cancer diagnosis and determination. TAAs and their antibodies-based detection of cancer have the advantages such as low-cost, and […]

Maximum Residue Limits (MRLs) for Veterinary Drugs in Foods.

Antibiotics are used for veterinary purposes almost as soon as they had been developed for human medicine. They are supplemented in the animal feed for growth promotion and treatment of infections, which are important during the development of intensive methods of animal husbandry, as a result there are major hazards that could be posed by […]

Products & Information Collection of Monkeypox virus (MPV)

Information of Monkeypox virus (MPV) Prevalence and Perniciousness of MPV Monkeypox is a rare disease that is caused by infection with monkeypox virus. Monkeypox virus belongs to the Orthopoxvirus genus in the family Poxviridae. The Orthopoxvirus genus also includes variola virus (which causes smallpox), vaccinia virus (used in the smallpox vaccine), and cowpox virus. Monkeypox was first discovered in 1958 […]

Tandem VHH/Nanobody (single domain antibody) – Introduction

Since 1975, monoclonal antibodies have been successfully used for the diagnosis and therapeutics. In 1993, heavy-chain-only antibodies which bind to antigens was discovered in camelids. The variable domain of heavy chain antibody (VHH) was called as nanobodies and it was anticipated as the better therapeutic antibodies in future due to its high stability, refoldability, and manipulable characteristics. […]

Format of bispecific antibodies (BsAbs)-C-terminal linker of Fc

ADAPTIR-FLEX platform technologies can be used to produce monospecific, bispecific, and multispecific immunotherapeutic proteins. These protein candidates bind to one or more targets found on tumor cells, immune cells, or other cells in the body or circulation to either amplify, suppress, or regulate the body’s defense mechanisms to treat cancer and autoimmune diseases. ADAPTIR-FLEX molecules […]

Format of bispecific antibodies (BsAbs)-VH-1-TCR C¦Á x VL-1-TCR C¦Â; VH-2-CH-2-Fc x VL-2-CL-2

WuXiBody, replace one parental mAb’s CH1/CL region by the T cell receptor (TCR) constant domain. WuXiBody’s design ensures cognate HC-LC pairing, the same goal as that being aimed by the CrossMab technology. BsAbs based on WuXiBody can adopt either asymmetric or symmetric format (Fig. 1). For asymmetric WuXiBody-based bsAbs, heterodimerization is promoted by the KiH […]

Format of bispecific antibodies (BsAbs)-VL1-CL1-VH2-CH2-Fc x VH1-CH1 x VL2-CL2

Tetravalent Fabs-In-Tandem immunoglobulins (FIT-Ig™) technology combines Fab fragments of any 2 parental mAbs create a tetravalent, dual-targeting single molecular entity, where the FabA is structurally fused to FabB in tandem at its N-terminus (Fig. 1a). A unique crisscross orientation of 2 sets of VH-CH1 and VL-CL evades any mispairing problem between two short chains and long chain. FIT-Ig have […]

Format of bispecific antibodies (BsAbs)-VH1-VH2-CH1-Fc1(G1) x VL2-VL1-CL-Fc2(G1)

CODV (cross-over dual variable domains) -Ig, contain four polypeptide chains that form two dual variable domains (four antigen binding sites) with a cross-over orientation (Figure 1), which is attained by inverting the alignment of the cognate domains on one chain. In order to adopt the correct VH/VL pairing, linker combinations were designed and optimized using […]

Format of bispecific antibodies (BsAbs)-scFv-Fab IgG

The XmAb enables alterations with desirable effects to the Fc domain of the antibodies. The modification increases affinity to the neonatal Fc receptor which prevents the antibody from degradation. Hence, this interaction extends the antibody’s halflife of this therapeutic drug. In order to construct the XmAb format an antibody heavy and light chain and a […]
