“…7 Apart from naturally occurring antibody formats, combinatorial deoxyribonucleic acid (DNA) technology has facilitated the development of recombinant antibodies such as fragment variable (Fv), disulfide-stabilized Fv antibody fragment, single-chain fragment variable (scFv), fragment antigenbinding (Fab), single-chain antibody fragment, divalent antibody formats such as minibody, diabody, F(ab′) 2 and (scFv) 2 , and multivalent forms such as tetrabodies, triomabs, triabodies, and F(ab) 3 . 8,9 Overview of conventional methods Selective antibody purification is commonly carried out using affinity chromatography or affinity-tag-based chromatography. It achieves high selectivity and purity; however, it becomes costly when utilized on a large-scale.…”

“…They are often the method of choice for antibody processing and more specifically, affinity-based methods are routinely used in the biopharmaceutical industry owing to the high selectivity and purity that can be achieved to meet regulatory and quality-control standards. 9 Innovations to improve the traditional methods such as biological-ligand-based methods are consistently investigated, while the use of complementary chromatographic techniques are now starting to achieve purities to match affinity-based techniques.…”

“…Tradicionalmente, a purificação dessas biomoléculas é realizada por meio da técnica de cromatografia de afinidade, empregando como ligantes a proteína A ou a proteína G imobilizadas (Huse et al, 2002). No entanto, esses ligantes apresentam algumas desvantagens, tais como o elevado custo, o risco de desnaturação do anticorpo e de desprendimento do ligante da matriz em decorrência das condições de eluição a baixos valores de pH e o risco da inativação do ligante após sucessivos ciclos de purificação (Ayyar et al, 2012). Diante desses inconvenientes, estudos têm sido desenvolvidos visando o emprego de técnicas alternativas à cromatografia de afinidade (Coleman e Mahler, 2003; Yu e Ghosh, 2010) ou de ligantes substitutos das proteínas A e G (Khoury e Lowe, Área temática: Processos Biotecnológicos 1…”

“…The total concentration of the human serum proteins was as high as 87.2 mg/mL and of high viscosity, so it was 10-fold diluted with 20 mmol/L PB (pH 6.0) (equilibration buffer) prior to loading. It should be noted that the dilution was also necessary to avoid protein aggregation when loading at high concentrations, which would block the binding sites and/or make the pores inaccessible [19]. Therefore, the serum feedstock was diluted in order for smooth purification operations by the affinity chromatography [20,21].…”
