R-M-1898 Iodoacetyl-LC-Biotin,cas:93285-75-7 Iodoacetyl-LC-Biotin (N-Iodoacetyl-N-Biotinylhexylenediamine or N-Biotinyl-N-(iodoacetyl)-1,6-hexanediamine) reacts with sulfhydryl groups to form stable thioether linkages. price>
R-M-1900 Biotin-NH-CH2CH2-S-S-pyr,CAS:112247-65-1 Biotin-NH-CH2CH2-S-S-Pyr is a cleavable disulfide linker for bio-conjugation that contains a terminal biotin group and a SSPy group. price>
R-M-1901 Biotin-PEG3-NH-Mal,cas:1431618-70-0 Biotin-PEG3-NH-Mal linker contains a biotin group and a maleimide group. The maleimide group specifically labels and crosslinks with cysteines and other sulfhydryls (at pH 6.5-7.5) and form a stable, irreversible thioether bond. The hydrophilic PEG spacer can increase aqueous solubility of the biotin conjugated molecules. price>
R-M-1902 UV-Tracer Biotin NHS Ester,cas:1628029-01-5   UV tracer biotin NHS ester( cas:1628029-01-5 ) is an ultraviolet tracer biotin NHS ester. price>
R-M-1903 SATA Protein Modifier,cas:76931-93-6 N-succinimidyl-S-acetylthioacetate (SATA) is a protein modification agent, used to protect free amine residues in proteins and peptides. price>
R-M-1906 BMPA Modifier,cas:7423-55-4 BMPA Modifier (N-ß-Maleimidopropionic acid) can be used as a protein crosslinker or sulfhydryl (-SH) to carboxylic acid (-COOH) modification reagent. price>
R-M-1907 EDC-HCl,cas:25952-53-8 EDC-HCl zero-length crosslinker is UltraPure, and is used to conjugate carboxyl functional groups to primary amines as found in peptides and proteins. price>
R-M-2054 OVA-NHS OVA-NHS,z Ovalbumin-NHS from ruixi.Ovalbumin(abbreviated OVA)is the main protein found in egg white.Ovalbumin has been used in the study of protein structure,proteomics and immunology.Ruixibio provides a variety of functionalized and bioconjugated ovalbumin conjugates.These labeled ovalbumin products were purified by size exclusion chromatography to remove non-conjugated molecules and ensure adequate applications both in-vitro and in-vivo. price>
R-M-5251 HRP-SH HRP-SH,Horseradish Peroxidase-thiol from ruixi.Horseradish peroxidase is a glycoprotein formed by the combination of colorless enzyme protein and brown iron porphyrin. It can be used in many biochemical detection projects and immune (ELISA) kits. price>
R-M-5282 Recombinant-Alkali tolerant Protein A(rat-PA) Protein A is a cell wall protein derived from Staphylococcus aureus that exhibits unique binding properties for IgG from a variety of mammalian species and for certain IgM and IgA as well. It binds with the fc region of immunoglobulins preferably through interaction with the heavy chain. It is conjugated to a wide variety of reporter molecules, including fluorescent dyes, enzyme labels, biotin, colloidal gold, and radioactive iodine for use in immunology and other biological research without affecting the binding site of antibody. rat-PA is improved in protein stability and tolerant to alkali by substitution of residues. It is also immobilized on solid matirxes such as agarose beads for the purification of IgG from ascetic fluid, serum, cultured supernatants, cell extracts or proteins of interest. For efficient covalent conjugation to the resin, a cysteine residue is inserted at the C-terminus of rat-PA.It is recommended that the product is reconstituted with sterile water into a final concentration of 10 mg/ml freshly. price>
