The physiological characteristics of exosomes has endowed them special function as biomarkers, therapy targets and drug carriers.
Creative Biostructure provides a comprehensive platform to help our client to expand the usage of exosome engineering for a specific diagnostic and therapeutic purpose. Exosomes as Diagnostic Biomarkers Exosomes are membrane vesicles secreted by all types of cells and are also discovered in the body fluids such as: saliva, blood, urine and breast milk. Exosomes are unique because its protein, lipid, RNAs contents provide additional hint for their identification. Therefore, exosomes have been considered as accessible diagnostic biomarkers with great potential for detection of many pathological conditions, including cancer.
Exosome Analysis and Characterization. Creative Biostructure’s exosome analysis and characterization service makes it easy to profile exosomal lipids, proteins and RNAs with our years of experience working on exosomes.
Our expertise provides comprehensive support for your exosome engineering study by including the following customized services. Exosome Isolation and Purification. The importance of exosomes in the pathology of key diseases have made them popular targets in both basic and pharmaceutical research, therefore, isolation of exosome becomes a prerequisite step before furthering their applications.
Creative Biostructure provide different techniques to isolate exosomes from various sample matrices. The Importance of Exosome Isolation and Purification As we know that exosomes are small endosome derived lipid nanoparticles (50-120 nm in diameter) secreted into extracellular space by most types of cells. Besides lipids, exosomal content also includes genomic DNA, RNA, proteins which is of great importance. There is cumulative evidence has suggested that exosomes have performed may biological functions particularly in cell-cell communication. Figure 1. Exosome Engineering. Creative Biostructure offers a complete set of service for exosome engineering to facilitate exosome applications.
We provide comprehensive support for your exosome engineering with the following customized services. The Importance of Exosome Engineering Exosomes become a promising carrier for therapeutic molecular delivery especially for cancer treatment due to its low immunogenicity, high biocompatibility, high drug delivery efficacy, and low cytotoxicity to normal tissue. First of all, exosomes are naturally endowed with efficient targeting surface moieties for tumor site. Atomic Force Microscopy (AFM) Service. Creative Biostructure provides images with near-atomic resolution for measuring surface topography using the Atomic Force Microscopy (AFM) technology.
The Atomic Force Microscope is applied to solve processing and materials problems in a wide range of technologies affecting the electronics, telecommunications, biomedical, chemical, automotive, aerospace, and energy industries. Technical Abilities Measurement:i. Topography (surface roughness, grain size, step height, etc.) at the angstrom scaleii. Super-Resolution Microscopy Service. Creative Biostructure has access to advanced super-resolution light microscopy facility allowing images to be taken with a higher resolution than the diffraction limit.
Super-resolution microscopy is a form of light microscopy, which can be applied to observe many biological structures not resolvable in conventional fluorescence microscopy. For example, new advances in this technique now give them the ability to image three-dimensional (3D) structures, measure interactions by multicolor colocalization, and record dynamic processes in living cells at the nanometer scale. Figure 1. Examples of super-resolution images of biological samples. Several far-field imaging methods are known to extend the diffraction-limited resolution to smaller values: Figure 2. Data Processing and Interpretation. Creative Biostructure now can provide a collection of tools and analysis package for biomolecular structure determination, refinement and analysis from crystallographic, EM or NMR data.
In structural biology field, in order to reveal a dedicated and reliable structure of biomolecule, research data is acquired, interpreted, published, reused, and sometimes eventually discarded. Creative Biostructure helps the development of appropriate infrastructural services, ones which make it easier and time-saving for researchers to collect, read and process the data and obtain the expected and target structure results.
Project Objectives With this deliverable, the project has reached or the deliverable has contributed to the following objectives, including but not limited to: Protein Expression Service. Proteins are the building blocks of all living organisms and play crucial roles in biological processes.
To investigate how a particular protein modulates biological processes, many aspects of the protein such as structure, modification, localization, interaction, and function needs to be studied. A considerable number of proteins, especially membrane proteins, are screened in drug discovery as biological targets or as potential drugs themselves. Most of these proteins are produced using cell-based or cell-free expression systems, which typically includes the transcription of recombinant DNA into mRNA that is further translated into the protein under study. Creative Biostructure uses both cell-based and cell-free systems to provide customized membrane protein expression services to customers in the pharmaceutical industry, as well as research institutions.

Our Zika Virus VLPs are composed of partially mature particles containing Envelope (E), pre-Membrane (prM) and Membrane (M). VLPs are produced in mammalian suspension cell cultures offering a suitable system for rapid scale up of manufacturing, without the risk of working with an infectious agent. The lack of infectivity of the product eliminates the need for chemical inactivation, which may compromise vaccine efficacy and safety. The particulate nature of the vaccine and the preservation of a variety of conformational antigenic sites may even render this vaccine efficacious in humans without using adjuvant if its incorporation into a vaccine raises safety concerns.
Zika virus is an emerging disease that is spread by Aedes mosquitoes. Ordering Process. Virus Like Particles (VLPs) Product Search All VLPs Products List Creative Biostructure provides virus-like particles (VLPs) products which are produced from recombinant E. coli, yeast, insect cells, or HEK293 cells. Our product line includes a wide variety of virus families including Parvoviridae (e.g. adeno-associated virus), Retroviridae (e.g. HIV), Flaviviridae (e.g. Hepatitis C virus) and bacteriophages (e.g.
Protein Crystallization. X-ray crystallography is currently the most favored method for structural determination of proteins and other macromolecules. The requisite for a successful X-ray crystallographic application is to obtain single crystals of the target protein. Data is then collected by diffracting X-ray from the single crystal that has an ordered pattern of atomic orientation. The assembly of atoms and molecules in the crystal can be deduced from the measurement of X-ray scattering. At present, more than 120,000 protein structures resolved by X-Ray crystallography experiments have been deposited in protein databank, accounting for nearly 90% of the resolved proteins, suggesting a predominant popularity of X-Ray crystallography in structural determination.
Fig.1. Custom Membrane Protein Services. Cell membrane functions as a boarder of cell by separating it from the outside environment, and the membrane proteins are the gateways to the cell. Nutrients, ions, waste products, even DNA and proteins are transported into and out of cells by membrane proteins. Membrane proteins involve in many cellular functions including: signaling transduction, cell adhesion, cell motility, transportation, and cell communication.
Given their important roles in cell functions, membrane proteins are often considered to be perfect drugs targets. Cryo-EM Services. Electron Microscopy(EM) has become an extremely popular method for the ultrastructural study of macromolecules, cells and tissues. An aqueous biological sample is frozen rapidly and irradiated with a beam of electrons. A detector senses how the electrons are scattered and a computer reconstructs the 3D-shape of the molecule. Why do you need this service? You have small amount of materials; The material is hard to crystallize; You are looking into the molecules in atomic details; It is a large biomolecular complex (>150 kDa, up to 2000 Å); You want to observe the real "native state" structure.
