The Ytterbium/ Holmium doped NaYF4 nanoparticles were synthesized by a modified thermal-decomposition method. Currently this product is spherical with a diameter from 10-15nm. The particles were stabilized with hydrophobic properties and can be dispersed in hexane or any other non-polar solvents, such as toluene and cyclohexane, to form a stable single phase colloidal solution. The emission intensity is higher than most of the fluorescence dye and could be noticed by naked eyes under regular in-door environment. The life time of the particles are close to unlimited due to the special mechanism. The fluorescence can’t be quenched by heat, surface modification, UV exposure, acid/base or aggregation. The particles can be easily modified to hydrophilic surface.
Most convenient Xeno-free and Serum-free culture media for or the growth and expansion of human fibroblasts and other mesenchymal cells. This medium is chemically defined and can be used for supporting the culture of cells in both 2D and 3D. This product replaces human or animal derived products, such as human and animal serum, and human and animal derived supplements. This product is packed in 10 convenient 50mL freezable medium bottles. No need to aliquot the big bottle anymore. Take one small bottle of medium to use and throw the remaining bottles in freezer for long term storage without worrying about the degradation of the medium components.
Integrins are receptors that facilitate cell-extracellular matrix (ECM) adhesion. Several types of integrins exist, and one cell may have multiple different types on its surface. Integrins are found in all animals. And total 16 integrins were found in vertebrates so far. We provide a complete integrin binding peptide array to help researchers to quickly identify the types of integrins on the cell surface. This kit can help researchers to quickly identify the types of integrin on the cell surface.
VS-PEG-VS is a linear homobifunctional PEG reagent with a thiol reactive vinylsulfone group on each side. VS group selectively reacts with free thiol, SH, sulfhydryl or mercapto groups.
VS-PEG-VS can be used as crosslinkers for PEGylation of proteins and peptides, nanoparticle and so on.
