A transmembrane protein (TM) is an integral membrane protein, which are embedded in the cell membrane. The transmembrane region, which directly interacts with the phospholipid bilayer and act as gateways to transport of specific substances across the membrane through signal pathways and cell metabolism. They regularly endure significant conformational changes to move a substance through the membrane. TM are highly hydrophobic, which aggregate […]

Human cytomegalovirus (HCMV) neutralizing antibodies (NAb) Human cytomegalovirus (HCMV) causes life-threatening illness in immunosuppressed patients. HCMV envelope proteins viz. glycoprotein B (gB), gH, gL, gO and UL128/UL130/UL131A are essential for the fusion of virus with the host plasma membranes to enter into the host cell. The gB protein is the direct mediator of cell fusion […]
Structure of capsid proteins is important to stimulate the immune response and it is depended on the post translational modification of different expression systems. The various expression systems such as prokaryotic (bacteria, yeast) or eukaryotic (baculovirus/insect cell, mammalian cell and plant) have been used to produce the VLP. In addition, cell-free expression systems have also […]
Influenza virus neutralizing Influenza is a transmissible acute respiratory disease caused by the influenza virus. The glycoprotein, hemagglutinin (HA) of influenza virus plays an important role during the viral infection. It helps the virus to bind the cell surface receptors, and transfer the genetic materials into the host cytoplasm through fusion. The neutralizing antibodies against […]
Zaire Ebola virus neutralizing antibodies (NAb) Zaire Ebola virus belongs to the family Filoviridae, which are highly lethal and it outbreaks since emerging in 1967, including a sustained epidemic in West Africa from 2013 to 2015. Zaire Ebolavirus (EBOV) glycoprotein (GP) is now the key target of antibodies. GP is composed of ectodomain GP1 and a trans-membrane […]
The natural structure of monoclonal antibodies provides a variety of possibilities for biological coupling. Chemical and specific natural (non engineering) antibody coupling has some advantages. It can avoid the complexity of antibody specific site mutation and the possible challenges in the amplification and optimization of cell culture. Coupling sites according to the antibody sequence, the […]
Apoptosis inducer (BCL XL inhibitor) Overexpression of anti apoptotic Bcl-2 family members (including BCL XL) is one of the mechanisms for cancer cells to obtain apoptosis resistance. Drugs that block the BH3 binding domain on BCL XL can trigger cancer cell apoptosis. Telanstadine and its analogues Targeted spliceosome is a large ribonucleoprotein complex involved in […]
There are so many payloads, like MMAE, Calicheamicin, MMAF, DM1, SN-38 and Dxd. Pyrrole benzodiazepines and indole chlorobenzodiazepines Pyrrolo [2,1-c] [1,4] benzodiazepine (PBD) is a natural product with antitumor activity. Their mode of action is selective alkylation in small grooves of DNA, in which the N2 of guanine forms a covalent bond with the electrophilic […]
There are so many payloads, like MMAE, Calicheamicin, MMAF, DM1, SN-38 and Dxd. Calendula Auristatins is an important payload used in ADC. The most famous family member MMAE exists in two listed drugs, adcetris and Polivy. At present, more than 10 kinds of ADCs with calendula (such as MMAE) or methylcalendula f (MMAF) […]
