Heterobifunctional PEG derivative that can be used to modify proteins, peptides and other materials via amino or other acid reactive chemical groups. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.
Physical Properties:
Off-white/white solid or viscous liquid depends on molecule weight;
Soluble in regular aqeous solution as well as most organic solvents;
Storage Conditions:
Store at -20 0C, dessiccated Protect from light. Avoid frequent thaw and freeze.
OVA FITC is one of Nanocs's fluorescent OVA conjugates that can be used for in-vivo imaging and other biomedical applications. Ovalbumin (abbreviated OVA) is the main protein found in egg white. Ovalbumin has been used in the study of protein structure, proteomics and immunology. Nanocs provides a variety of functionalized and bioconjugated ovalbumin conjugates. Our fluorescein labeled OVA (FITC-OVA) is a green fluorescent OVA conjugate that has strong fluorescence around 515 nm upon excited at 488 nm excitation wavelength.
Specifications:
Conjuate substrate: OVA (Ovalbumin);
Conjugate dye: Fluorescein (FITC);
Form: Aqueous solution or lyophilized powder;
Color: Yellow or orange;
Ex/Em Wavelength: 495 nm/515 nm;
Conjugation ratio: 5~10 fluorescein (FITC) on each OVA molecule.
Biotinylated silica nanoparticles or microbeads from Nanocs have narrow size distribution yet with multiple size selection from 20 nm to 50 microns. Standard deviation of these particles is in the range of 10% of listed size parameter. Our biotin beads were synthesized by covalently attaching biotin ligands on the surface of these silica beads and therefore, they are very stable in various solution. In addition, our biotinylated silica beads have high biotin loading capacity and therefore, strong binding capability torward avidin or streptavidin. These biotinylated particles have wide applications in diagnostic reagents and bioassay development. They can be further modified with different surface coatings and functional groups. We also provide fluorescent biotin silica beads for bioassay development. Nanocs surface modified silica particles provide more choices for in-vitro or in-vivo applications of those nanoparticles. Customer conjugation and modification is available upon request.
