R-C-895	Simultaneous modification of folic acid / azide by sialic acid	Sialic acid is a general term for a class of derivatives of neuraminic acid in which amino hydrogen or hydroxyl hydrogen is substituted.It also refers to N-acetylneuraminic acid,one of the most important members of such compounds. Sialic acid is widely distributed in animal tissues and a small amount in other organisms,mainly as a component of glycoprotein and ganglioside.	price>
R-C-903	Plant carbon point customization	As a new kind of zero dimensional carbon based nano fluorescent materials, carbon dots have attracted much attention.Due to its simple preparation,low toxicity,biocompatibility,easy functionalization,photobleaching resistance and fluorescence tunability,carbon dots have shown great potential in the field of biology.	price>
R-C-904	Fingolimod hydrochloride-biotin	Fingolimod Hydrochloride is the hydrochloride salt form of fingolimod,an orally available derivate of myriocin and sphingosine-1-phosphate receptor 1(S1PR1, S1P1)modulator,with potential anti-inflammatory and immunomodulating activities. Upon oral administration,fingolimod,as a structural analogue of sphingosine, selectively targets and binds to S1PR1 on lymphocytes and causes transient receptor activation followed by S1PR1 internalization and degradation.	price>
R-C-905	FITC labeled 388 active substance	FITC fluorescein isothiocyanate is a commonly used method to label antibody. FITC is usually yellow,brown or brownish yellow powder or crystal with stable properties and can be stored for several years at low temperature.Under alkaline conditions,the carboamide bond of FITC can covalently bind with lysine amino group on antibody protein to form FITC protein conjugate,namely fluorescent antibody or fluorescent conjugate.	price>
R-C-908	Stick shape Fe3O4（100nm）	Fe3O4 has stable material properties,good compatibility with organisms,high strength and magnetism.In the aspect of targeted drug carrier,magnetic targeted nano drug carrier can directly reach the lesions through the effect of external magnetic field after loading the components of drugs,which can reduce the side effects of drugs on other organs and tissues,and improve the efficacy and enhance the therapeutic effect.	price>
R-C-909	Furan modified sodium alginate	Sodium alginate is a by-product of extracting iodine and mannitol from kelp or Sargassum.Its molecule is composed of β-D-mannuronic acid (m) and α-L-guluronic acid(g)by(1→4)bonds.It is a natural polysaccharide with the stability,solubility,viscosity and safety required for pharmaceutical excipients.	price>
R-C-911	Oleic acid coated scintillators	Scintillator is a kind of material that can emit light after absorbing high-energy particles or rays.It plays a very important role in the field of radiation detection.It is usually processed into crystal in application,which is called scintillation crystal.Rare earth nanocrystalline scintillators are characterized by easy size control,colorless transparency,good dispersion and excellent afterglow performance.	price>
R-C-912	Chitosan coated gold nanoparticles	Nanoparticles are solid colloidal particles with the size of 10~1000 nm,which can be used as drug delivery carriers.Nano drug delivery system is a new drug carrier produced by nano drug delivery technology.It has the characteristics of targeting,controlled release and surface modifiability.It can effectively pass through the mucosal surface and transport into the systemic circulation. Chitosan has excellent biocompatibility and bioadhesion as a new drug carrier.	price>
R-C-913	Galactose-VK19	Galactose(CH2OH(Choh)4cho)is a kind of monosaccharide,which can be found in dairy products or sugar beet.Galactose is a monosaccharide composed of six carbons and one aldehyde group,which is classified as aldose and hexose.It often exists in the form of d-galactoside in brain and nerve tissues,and is also an important component of some glycoproteins.The monosaccharide absorbed most quickly in the intestine is galactose.	price>
R-C-916	QSY21-NHS	The amine reactive quencher QSY 21 succinimidyl ester has a broad and intense absorption 661 nm maxima but no fluorescence making it useful as an acceptor in fluorescence resonance energy transfer FRET applications.	price>
