Challenges for the effective molecular imprinting of proteins

Abstract: Molecular imprinting is a technique that is used to create artificial receptors by the formation of a polymer network around a template molecule. This technique has proven to be particularly effective for molecules with low molecular weight (<1500 Da), and during the past five years the number of research articles on the imprinting of larger (bio)templates is increasing considerably. However, expanding the methodology toward imprinted materials for selective recognition of proteins, DNA, viruses and bacteria a… Show more

“…Imprinted protein structures on the surface or inside of nano/micron-sized particles can be used to study protein-protein interactions in an alternative way, as an antibody analog or since there is specific binding it can also act as a scavenger particle [76][77][78]. For the incorporation one can use electrostatic interactions to coordinate the protein structure but it can also first be confined to a surface covalently after which a layer can be built in between the surface bound proteins, upon removal a void in the shape of the protein is formed [79]. The surface binding approach has recently been used to actively scavenge virus particles from solution [80].…”

“…Наиболее часто используемые белки-шаблоны для получения МИП -альбумин, гемоглобин, лизоцим [17]. Для получения полимеров с молекулярными отпечатками применяют 2D-структуры, то есть схемы для получения плоских поверхностей, покрытых полимерами.…”

“…Анализ связывания лизоцима по сравнению с цитохромом с в качестве конкурирующего белка показал преимущественное связывание лизоцима с фактором селективности для МИП-поверхности, равным 9,8, а для НИП-поверхности -2,9 [33]. Импринтирование в объёме (3D-структуры) как правило, характеризируется сложностью диффузии шаблона в полимер, однако получены МИП на основе акриламидных гидрогелей с использованием в качестве шаблона цитохрома с, лизоцима (в концентрационном диапазоне 0,5-4 мг/мл), гемоглобина (0,125 мг/мл -1 мг/мл) [17,34]. Анализ белков проводился спектральными методами по регистрации поглощения ароматических аминокислот при 280 нм, по поглощению гема при 410 нм для гемопротеинов гемоглобина, миоглобина и цитохрома с или колориметрически с использованием метода Бредфорд [35].…”

“…4,5,[16][17][18] In addition, the large molecular size of proteins results in poor mass transport and permanent entrapment within traditionally dense MIP gels, while high elasticity and porosity of a looser gel makes the imprinting process less selective. [18][19][20] Consequently, it is still a severe challenge to nd efficient and general ways to imprint proteins.…”
