Format of bispecific antibodies (BsAbs)-Dual-affinity re-targeting antibody

Dual-affinity re-targeting proteins (DARTs) encompasses of two Fv fragments, containing two single antigen-binding sites formed when two Fv fragments heterodimerize. The Fv1 contains of a VH from antibody A and a VL from antibody B, whereas Fv2 contains VH from antibody B and VL from antibody A in the order of VL (1)-VH (2) and […]

Format of bispecific antibodies (BsAbs)-Tandem scFv

A tandem scFv links two or more scFvs with the helical peptide linkers in the orientation NH2–VL1–VH1–(linker–VL2–VH2)n–COOH, resulting in a single chain bivalent and bi-specific molecule encoded by a single gene (Figure 2). Tandem scFv can be used to target two different antigens on two different cells, two different antigens on the same cell, or […]

Format of bispecific antibodies (BsAbs)-Tandem VHH

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. […]

Diagnostic antibodies and antigens for biologics testing: Streptavidin (SA), Staphylococcus protein A (SPA)

Full List Download The biological agent such as streptavidin and staphylococcus protein A have an important role in biochemical research because of its ability to bind biotin and immunoglobulins respectively. GENEMEDI produces core diagnostic ingredients such as streptavidin, staphylococcus protein A and so on for the biochemical research. Classification: Streptavidin (SA) Staphylococcus protein A (SPA)

Diagnostic antibodies and antigens for multiple disease testing: thioredoxin reductase (TrxR)

Thioredoxin (Trx) and thioredoxin reductase (TrxR) plus NADPH, comprising the thioredoxin system, has a large number of functions in DNA synthesis, defense against oxidative stress and apoptosis or redox signaling with reference to many diseases such as cancer, viral disease, ischaemia– reperfusion injury, cardiac conditions, aging, premature birth and newborn physiology. GENEMEDI produces core diagnostic […]

Diagnostic antibodies and antigens for Neurodegenerative diseases testing: Phospho-tau181 (p-tau181), Phospho-tau217 (p-tau217), tau proteins (Tau), neurofilament light chain (NFL), neurofilament protein (AD7c-NTP)

Neurodegenerative diseases refer to the injury or dysfunction of one or more nerves, which results in numbness, tingling, muscle weakness and discomfort in the nerves affected part. Alzheimer’s disease (AD) is a progressive neurodegenerative disease most often characterized by initial memory impairment and cognitive decline that can ultimately affect behavior, speech, visuospatial orientation and the […]

Diagnostic antibodies and antigens for Fibrinogen disorders testing: Fibrinogen (FIB)

Fibrinogen disorders are a set of hereditary or acquired abnormalities in the quantity and/or quality of circulating fibrinogens. The disorders may lead to pathological bleeding and/or blood clotting or the deposition of fibrinogen in the liver, kidneys, or other organs and tissues. These disorders include Congenital afibrinogenemia, Congenital hypofibrinogenemia, Fibrinogen storage disease, Congenital dysfibrinogenemia, Hereditary […]

Diagnostic antibodies and antigens for Vitamin deficiency testing: folic acid (FA), vitamin D binding protein (VDBP)

Vitamin deficiency is the condition of a long-term lack of a vitamin. Vitamin deficiency caused by insufficient intake of vitamin is classified as a primary deficiency, whereas vitamin deficiency due to an underlying disorder such as malabsorption is called as a secondary deficiency. Vitamin deficiencies can be detected in several ways. GENEMEDI produces core diagnostic […]

Diagnostic antibodies and antigens for metabolic diseases testing: 25-OH-(VD3+VD2), PINP, β-CTx, 25-OH-VD, 25-OH-VD-3, SAHH, CBL, CBS, LP-PLA2, RBP4

Metabolism is the process of making energy from the food. metabolic disease, any of the diseases or disorders that disrupt normal metabolism, the process of converting food to energy on a cellular level. Thousands of enzymes participating in numerous interdependent metabolic pathways carry out this process. Metabolic diseases affect the ability of the cell to […]

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 […]
