Microbial expression of Exendin-4 analog and its efficacy in mice model.

Exendin-4 is a GLP 1 agonist incretin-mimetic peptide hormone comprising 39 amino acids. Exenatide (Byetta) is a chemically synthesized version of Exendin-4 with an additional C-terminal amidation. Exenatide acts as a GLP-1 receptor agonist.

Charge variant analysis of proposed biosimilar to Trastuzumab.

Trastuzumab is a humanized monoclonal antibody (mAb) employed for the treatment of HER2 Positive Breast Cancer. A HER2 overexpressing tumor cell binds to Trastuzumab and attracts immune cells which lead to induction of Antibody Dependent Cellular Cytotoxicity (ADCC) by binding to Fc receptors (CD16a or FcγRIIIa) on an effector cell, such as natural killer (NK) cells. The most commonly expressed receptor on NK cell is CD16a which binds to the Fc portion of Trastuzumab.
