Azido-PEG24-NHS ester is a PEG derivative containing an azide group and an NHS group. The azide group enables Click Chemistry. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer adds to the water solubility of this reagent. https://www.cd-bioparticle...

CD Bioparticles offers custom services to help you develop your cell sorting process to obtain your target cell population via magnetic activated cell sorting (MACS). MACS is a highly specific and rapid magnetic particle-based cell sorting technique widely used in immunology, stem cell research, oncology and clinical medicine. Antibody-conjugated magnetic particles are used to capture the antigen on the surface of target cells and are adsorbed to the sidewall of the magnetic field. The unlabeled cells without magnetic particle binding are removed from the cell suspension. CD Bioparticles provides customized antibody-conjugated magnetic nanoparticles and cell-sorting validation services. https://www.cd-bioparticle...

Penetration can occur into the membrane without necessarily diffusing, or passing through, the membrane. Permeation is the movement of the permeant through the membrane that encompasses first partitioning the membrane and then diffusion through the membrane. Penetration and permeation tests are used to profile the permeation behavior of pharmaceutical compounds that can cross cell membranes by passive diffusion, active transport, and pinocytosis to reach the systemic circulation. Penetration and permeability can depend on a variety of factors, such as pH, hydrophilicity and other physico-chemical properties of drugs, and tissue species. As bioparticles are formulated to increase drug penetration and absorption, especially for transdermal drugs, it is important to measure their penetration and permeation abilities to assess drug effectiveness. https://www.cd-bioparticle...

Poly(propylene glycol) (PEG) is a polymer commonly used for drug delivery. Its superior biocompatibility and water solubility make it an ideal drug carrier. PEG can improve the solubility of drugs, prolong the circulation time of drugs in the body, and slow down the metabolism and excretion rate of drugs, thereby improving drug efficacy. In addition, PEG can also reduce drug toxicity to tissues and alleviate adverse reactions during drug delivery. Due to its excellent performance, PEG has been widely used in nano drug carriers, colloidal delivery systems, etc., bringing important breakthroughs and innovations to the field of drug delivery. https://www.cd-bioparticle...

DiagPoly™ Europium Streptavidin Polystyrene Nanoparticles, 300 nm (#DES-T002) are polystyrene or polystyrene with coploymer grafted surface. The particles are chelated with Eu (excitation: 333 nm, emission: 613 nm, red fluorescence) for extremely broad stokes shift which can prevent non-specific fluorescence interference. 300 nm europium polystyrene nanoparticles are modified with streptavidin for binding biotinylated molecules with a quite high degree of specificity and affinity. The density of particle solution is 1.06 g/cm3. Each carboxylate group will provide 20 A2 for binding on the surface. https://www.cd-bioparticle...

Nanoparticles are used as carriers for drug delivery, and their own safety to organisms or cells is receiving increasing attention. As a drug carrier, in addition to the nature of the carrier, it also has less toxicity to the organism. In this way, the side effects of the drug carried by nanoparticle can be effectively reduced, and the applicability of the drug delivery system can be improved. Therefore, the assessment of the toxicity of nanoparticles for transporting drugs is an essential parameter for the construction of nanoparticle drug delivery systems. Various methods are available for the toxicity assessment, which can be categorized as In vitro and in vivo. Generally, In vitro methods used to assess nanoparticle toxicity fall into two general categories: functional assays and viability assays. Functional assays are those that seek to assess the effects of nanoparticles on various cellular processes, whereas viability assays are concerned solely with whether a given nanoparticle causes death in a cell or a system of cells. The in vivo toxicity assessment is normally performed on animal models such as mice and rats. https://www.cd-bioparticle...
