The specificity and affinity characteristics of antibodies make them excellent probes in biosensor applications. Unfortunately, their large size, unstable behavior, and random immobilization properties create numerous problems. The single-domain antigen-binding fragment derived from heavy-chain antibodies of camelids (termed VHH) offers special advantages in terms of size, stability, and ease o...
Due mainly to properties such as high affinity and antigen specificity, antibodies have become important tools for biomedical research, diagnosis, and treatment of several human diseases. When the objective is to administer them for therapy, strategies are used to reduce the heterologous protein immunogenicity and to improve pharmacokinetic and pharmacodynamic characteristics. Size minimization...
The mouse T (Brachyury) gene is required for early mesodermal patterning. Mice homozygous for mutations in T die at midgestation and display defects in mesodermal tissues such as the notochord, the allantois and the somitic mesoderm. To examine the role of T in patterning of somitic and posterior mesoderm along the anterior-posterior axis, we have examined the expression of a panel of molecular...
We have isolated zebrafish nk2.2, a member of the Nk-2 family of homeobox genes. nk2.2 is expressed in a continuous narrow band of cells along a boundary zone demarcating the location at which two of the earliest nuclei in the brain differentiate. This band of cells is located within a few cell diameters of cells expressing the signalling molecule sonic hedgehog/vertebrate hedgehog-1 (shh/vhh-1...
Amyloid diseases such as Alzheimer's and thrombosis are characterized by an aberrant assembly of specific proteins or protein fragments into fibrils and plaques that are deposited in various tissues and organs. The single-domain fragment of a camelid antibody was reported to be able to combat against wild-type human lysozyme for inhibiting in-vitro aggregations of the amyloidogenic variant (D67...
زمینه و هدف: آنتی بادی های زنجیره سنگین شتری Camelied-derived heavy chain) (VHH= یک آنتی بادی شتری بوده و کوچک ترین واحد باند شونده به آنتی ژن است. اندازه کوچک نانوبادی ها بزرگ ترین مزیت آن ها می باشد که سبب دستکاری ژنتیکی راحت آن ها می شود. این مطالعه با هدف ساخت کتابخانه ی آنتی بادی تک دمین از شتر ایمن شده با یک رده سلولی آدنوکارسینومای سینه ی انسان (SKBR3) طراحی و اجرا شد. روش بررسی: در این ...
Vibrio harveyi VHH hemolysin is a putative pathogenicity factor in fish. In this study, the hemolysin gene vhhA was overexpressed in Escherichia coli, and the purified VHH was characterized with regard to pH and temperature profiles, phospholipase activity, cytotoxicity, pathogenicity to flounder, and the signal peptide.
