Cardiolipin (CL) is a unique phospholipid with a very interesting chemical and specific ultrastructural characteristics. It is a highly acid dimer of phosphatidylglycerol (PG) and phosphatidic acid (PA), containing four acyl chains; three glycerols and two phosphate headgroups. Due to deprotonation of one of one of these phosphate groups, cardiolipin is negatively charged in physiological pH. https://www.cd-bioparticles.net/p/10387/cl-liposomes

Gene expression and therapy is the introduction of foreign nucleic acids into target cells to modify or compensate for gene defects, so as to treat diseases such as cancer, diabetes, autoimmune diseases and infectious diseases. The rate of removal of exposed nucleic acid is faster, and the rate of non-specific biological distribution and cell internalization is low, which cannot achieve the expected therapeutic effect. Non-viral vectors have low immunity, can be used for multiple injections and mass production, and have great potential for clinical gene therapy. Common non-viral vector transgenic methods include electroporation, calcium phosphate precipitation, and liposomes. https://www.cd-bioparticles.net/gene-expression

A fully validated dissolution in vitro release method is one of the control tools to ensure that quality and clinical performance are maintained throughout the lifecycle of the drug products. For example, in vitro release methods may aid in the characterization of liposome integrity, and in quantifying free versus encapsulated drugs. Like drug products without nanomaterials, drug products containing nanomaterials should have dissolution/in vitro release methods capable of discriminating formulation and manufacturing differences which may impact the clinical performance of the drug product. In addition to in vitro drug release, drug in vitro testing also includes in vitro toxicity test, in vitro drug sensitivity tests and so on. https://www.cd-bioparticles.net/drug-in-vitro-testing

The pull-down assay is a technique developed to verify the physical interactions between proteins in vitro, which can be also used to confirm a predicted protein-protein interaction and identify novel interacting partners. Although this method can't reflect the real interaction under physiological conditions due to the uncertain spatially encounter in vivo, it is a powerful tool for studying protein-protein interactions in vitro. This method typically involves the affinity capture process using bait protein coupled supports and various wash and elution steps, which are tedious and time-consuming. https://www.cd-bioparticles.com/products/pull-down-kit-1070.html

Silane-PEG-Maleimide (Silane-PEG-Mal) is a linear heterobifunctional PEG reagent with a maleimide and a silane.It is a useful crosslinking reagent with a PEG spacer. Maleimide reacts with thiol, SH, sulfhydryl or mercapto, and silane group can react with glass or other hydroxylated surface or particle.It may be used to introduce thiol or cysteine reactive functional group on hydroxylated nanopartilce, microsphere, self-assembled monolayer or metal chips. Pegylation can greatly suppress the non-specific binding of charged molecules to the modified surfaces. And they have wide applications for medica device, biomems or biocompatible material development.
