Process chromatography forms the core of purification of biotherapeutics. The unparalleled selectivity that it offers over other alternatives combined with the considerable robustness and scalability make it the unit operation of choice in downstream processing. It is typical to have three to five chromatography steps in a purification process for a biotherapeutic. Generally, these steps offer different modes of separation such as ion-exchange, reversed phase, size exclusion, and hydrophobic interaction. In the past decade, multimodal chromatography has emerged as an alternative to the traditional modes. It involves use of more than one mode of separation and typically combines ion-exchange and hydrophobic interactions to achieve selectivity and sensitivity. Over the last decade, numerous authors have demonstrated the significant potential that multimode chromatography offers as a protein purification tool. This review aims to present key recent developments that have occurred on this topic together with a perspective on future applications of multimodal chromatography.

Colorectal cancer is the third most common form of cancer and the second leading cause of cancer-related death in the Western world. The answers to such life threatening diseases and cancers are monoclonal antibodies (MAb's) which are widely used as therapeutic agents. World demand for currently approved MAb's is on the order of a few kilograms per year. However, new therapeutic MAb's are under development and require doses of several hundred milligrams to a gram over the course of therapy. Very often to cater for the special requirements for the growth of mammalian cells, serum is added to the cell culture medium. However, removal of serum from the cell culture medium is often carried out, especially if the end product is to be used for human consumption, in order to eliminate various disadvantages such as high physiological variability, high batch to batch variability, risk of contamination and high cost, and challenges posed in the downstream processing of the product. In this paper, the adaptation of cholesterol requiring NS0 cells to commercially available serum free media is presented. ABSTRAK: Kanser kolorektum merupakan kanser ketiga paling umum dan kini berada di tempat kedua penyebab kematian berkaitan kanser di negara Barat. Jawapan kepada penyakit yang mengancam nyawa dan penyakit kanser adalah antibodi monoklon (monoclonal antibodies ((MAb's)) yang digunakan sebagai agen terapeutik. Permintaan dunia terhadap MAb's yang diluluskan adalah dalam bilangan beberapa kilogram setahun. Namun, terapeutik MAb's yang baru adalah di bawah penyelidikan dan memerlukan beberapa ratus dos milligram hingga satu gram dalam satu peringkat terapi. Sering kali untuk memenuhi permintaan terhadap tumbesaran sel mamalia, serum dicampurkan dengan sel kultur perantara. Walaupun begitu, pemindahan serum dari sel kultur perantara sering dilakukan, terutamanya jika produk akhir digunakan untuk kegunaan manusia; untuk mengurangkan pelbagai kelemahan seperti kebolehubahan psikologi yang tinggi, kebolehubahan yang tinggi daripada satu kumpulan ke satu kumpulan lain, risiko pencemaran, kos yang tinggi, dan cabaran mendatang dalam pemprosesan produk. Dalam perbentangan ini, kolestrol yang diubah memerlukan sel NS0 yang dikomersilkan dengan serum bebas perantara.
