Expression Enhancement in Trastuzumab Therapeutic Monoclonal Antibody Production using Genomic Amplification with Methotrexate

BACKGROUND Trastuzumab (Herceptin) is a humanized monoclonal antibody (mAb) which is used for specific treatment of metastatic breast cancer in patients with overexpression of HER2/neu receptor. In this study, we have attempted to develop a biosimilar version of trastuzumab mAb. METHODS According to in silico studies, the heavy and light chains of trastuzumab mAb were designed and constructed...

Trends in capacity utilization for therapeutic monoclonal antibody production.

The administration of high doses of therapeutic antibodies requires large-scale, efficient, cost effective manufacturing processes. An understanding of how the industry is using its available production capacity is important for production planning, and facility expansion analysis. Inaccurate production planning for therapeutic antibodies can have serious financial ramifications. In the recent ...

Alternatives in monoclonal antibody production.

Therapeutic monoclonal antibody for sporotrichosis

Sporotrichosis is a chronic subcutaneous mycosis that affects both humans and animals worldwide. This subcutaneous mycosis had been attributed to a single etiological agent, Sporothrix schenckii. S. schenckii exhibits considerable genetic variability, and recently, it was suggested that this taxon consists of a complex of species. Sporotrichosis is caused by traumatic inoculation of the fungus,...

The therapeutic monoclonal antibody market.

Since the commercialization of the first therapeutic monoclonal antibody product in 1986, this class of biopharmaceutical products has grown significantly so that, as of November 10, 2014, forty-seven monoclonal antibody products have been approved in the US or Europe for the treatment of a variety of diseases, and many of these products have also been approved for other global markets. At the ...

Cloning and Expression of the Variable Regions of Anti-EGFR Monoclonal Antibody in E. coli for Production of a Single Chain Antibody

Background:Epidermal growth factor receptor (EGFR) overexpression is a characteristic of several malignancies and could be considered as an excellent target for designing specific inhibitors such as anti-EGFR monoclonal antibodies for cancer therapy. Drawbacks exerted by large sizes of full-length antibodies have lead to the development of single chain antibodies, which benefit from having smal...
