Book Description
"This volume focuses on applications of split inteins, and the progress that has been made in the past 5 years on discovery and engineering of fast and more efficient split inteins. The first few chapters in Split Inteins: Methods and Protocols explore new techniques on how to use split inteins for affinity purification of overproduced proteins, and split-intein based technologies to prepare cyclic peptides and proteins. The next few chapters discuss semisynthetic protein trans-splicing using one synthetic intein piece, synthetic intein-extein pieces used to deliver other cargos for chemical modification both of purified proteins and of proteins in living cells, as well as isotopic labeling of proteins for NMR studies, and a discussion on how protein block copolymers can be generated by protein trans-splicing to form protein hydrogels. The last few chapters deal with intein applications in transgenic plants and conditional inteins that can be regulated in artificial ways by small molecules or light, a cassette-based approach to quickly test many intein insertion positions, and a computational approach to predict new intein split sites (the approach also works for other proteins). Written in the highly successful Methods in Molecular Biology series format, chapters include introduction to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Split Inteins: Methods and Protocols is a valuable resource that will provide guidance toward possibilities of split intein applications, explore proven and detailed protocols adaptable to various research projects, and inspire new method developments."--OCLC.

Book Description
This volume presents detailed laboratory protocols for in vitro synthesis of mRNA with favorable properties, its introduction into cells by a variety of techniques, and the measurement of physiological and clinical consequences such as protein replacement and cancer immunotherapy. Synthetic techniques are described for structural features in mRNA that provide investigational tools such as fluorescence emission, click chemistry, photo-chemical crosslinking, and that produce mRNA with increased stability in the cell, increased translational efficiency, and reduced activation of the innate immune response. Protocols are described for clinical applications such as large-scale transfection of dendritic cells, production of GMP-grade mRNA, redirecting T cell specificity, and use of molecular adjuvants for RNA vaccines. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Synthetic mRNA: Production, Introduction into Cells, and Physiological Consequences is a valuable and cutting-edge resource for both laboratory investigators and clinicians interested in this powerful and rapidly evolving technology.

Book Description
Over the past two decades, inteins have been extensively used in a wide variety of applications in biotechnology. Split inteins are a subset of inteins, which are identified more recently and expressed in two separate segments naturally. They catalyze the splicing reaction in trans upon association of the two halves. Due to their unique features, split inteins offer improved controllability and flexibility in trans-splicing and trans-cleaving over the previous tools based on contiguous inteins. The engineered split inteins would allow the development of efficient self-cleaving affinity tags for purification applications and new methods for protein conjugation. In this work, an engineered split intein derived from Nostoc punciforme (Npu) was applied in a column-free purification strategy in combination with the aggregating tag, elastin-like polypeptide (ELP), as an initial capture step for recombinant proteins expressed in E. coli. Meanwhile, on-column purification strategy using the same engineered split intein was employed for the production of value-added biosimilar target, Granulocyte-colony stimulating factor (G-CSF). To adapt the split intein-based purification platform for the production of protein therapeutics expressed in mammalian cells, multiple leader sequences were designed and screened for optimal expression and secretion of intein-tagged precursor proteins. Moreover, the extein dependency of this engineered Npu split intein was thoroughly characterized by using in solution cleaving kinetics study and Forster Resonance Energy Transfer (FRET) based high-throughput method. The information gathered guides for fast and consistent cleavage reactions among various target proteins and provides insight to the cleavage mechanism. In this work, the trans-splicing properties of split inteins were also exploited for developing novel bioconjugation methods onto fluorescent nanodiamonds. Two split inteins, Gos-TerL and GP41.1, were used for the development of N-terminal and C-terminal oriented bioconjugation schemes, respectively. The new methods would allow rapid and spontaneous immobilization of proteins onto fluorescent nanodiamond surfaces for applications such as biomedical imaging or drug delivery.

Book Description
"Molecular Gels: Materials with Self-Assembled Fibrillar Networks" is a comprehensive treatise on gelators, especially low molecular-mass gelators and the properties of their gels. The structures and modes of formation of the self-assembled fibrillar networks (SAFINs) that immobilize the liquid components of the gels are discussed experimentally and theoretically. The spectroscopic, rheological, and structural features of the different classes of low molecular-mass gelators are also presented. Many examples of the application of the principal analytical techniques for investigation of molecular gels (including SANS, SAXS, WAXS, UV-vis absorption, fluorescence and CD spectroscopies, scanning electron, transmission electron and optical microscopies, and molecular modeling) are presented didactically and in-depth, as are several of the theories of the stages of aggregation of individual low molecular-mass gelator molecules leading to SAFINs. Several actual and potential applications of molecular gels in disparate fields (from silicate replication of nanostructures to art conservation) are described. Special emphasis is placed on perspectives for future developments. This book is an invaluable resource for researchers and practitioners either already researching self-assembly and soft matter or new to the area. Those who will find the book useful include chemists, engineers, spectroscopists, physicists, biologists, theoreticians, and materials scientists.
