R-L-160	Recombinant Streptavidin 2,r-SA2	Recombinant streptavidin 2 (r-SA2) is modified from native streptavidin at the molecular level by removing the binding force to form tetramers. r-SA2 is an active monomer, but its affinity for biotin is strongly weakened (Kd≈10-7M), achieving reversible binding and dissociation. Thus, it can be used for the gentle separation and purification of proteins, antibodies, nucleic acids and other biotinylated materials.	price>
R-L-161	Recombinant Core Streptavidin 3,r-cSA3	Recombinant central streptavidin 3 (r-cSA3) is modified from native streptavidin at the molecular level by removing the binding force to form tetramers. r-cSA3 is an active monomer, but its affinity for biotin is strongly weakened (Kd≈10-7M), achieving reversible binding and dissociation. It can be used for gentle separation and purification of proteins, antibodies, nucleic acids and other biotinylated materials.	price>
R-L-162	Recombinant Core Streptavidin 4,r-cSA4	In theory, an SA can bind four biotinylated macromolecules, but due to the spatial barrier in biotinylated macromolecules, SA generally cannot bind 1-2 biotinylated macromolecules. We have optimized the spatial structure of streptavidin 4 at the molecular level, which leads to advantages in binding with biotinylated macromolecules. Our designed product can bind 2-4 biotinylated macromolecules, and its stability is also higher than common SA or SA core. It is suitable for scientific research, diagnostic testing and other fields.	price>
R-L-167	Biotin-DBCO,Biotin-Dibenzocyclooctyne	This biotin derivative bears a terminal DBCO group. It can be used to prepare various biotinylated conjugates via Click Chemistry. Biotin can be subsequently detected e.g. via streptavidin or avidin. DBCO alkynes allow to perform click reactions with azide-modified targets without the use of heavy metal catalysis via a strain-promoted azide-alkyne click reaction (SPAAC).	price>
R-R-0193	BSA-glucocorticoid	BSA-glucocorticoid/Bovine serum albumin-glucocorticoid refers to a conjugate of glucocorticoid hormone (such as cortisol or dexamethasone) covalently linked to bovine serum albumin (BSA).BSA-glucocorticoid conjugates can provide important insights into the pharmacokinetics and pharmacodynamics of glucocorticoids, allowing researchers to better understand their interactions with cells and tissues. Additionally, these conjugates can be utilized in the development of new drug delivery systems and targeted therapies.	price>
R-R-0214	BSA-hydrazide	BSA-hydrazide refers to a conjugate formed by attaching hydrazide molecules to Bovine Serum Albumin (BSA).BSA-hydrazide offers a versatile and customizable tool for various biomedical, biotechnological, and bioanalytical applications. Its ability to react with aldehydes or carbonyl compounds allows for the specific conjugation or surface immobilization of BSA, enabling researchers to create tailored biomaterials and develop novel assays or drug delivery systems.	price>
R-R-0232	Pentynoic acid STP ester CAS: 1807530-14-8	Pentynoic acid STP ester CAS: 1807530-14-8. This water soluble alkyne activated ester reagent is used for the attachment of alkyne group to variois biomolecules such as proteins, and peptides. Amino-DNA, and other amines can be used as well. Since natural proteins do not contain alkynes, but almost always contain amines (lysines), this molecule is an "adaptor" to turn natural amines into alkynes.	price>
R-R-0241	Methacrylated-collagen	Methacrylated collagen is a modified form of collagen, which is a natural protein found in connective tissues. Methacrylated collagen is commonly used in tissue engineering and regenerative medicine applications. The modified collagen can serve as a biocompatible and biodegradable scaffold for cell growth and tissue regeneration. It can be used to create 3D structures, such as hydrogels or films, that mimic the extracellular matrix and support cell attachment, proliferation, and differentiation.	price>
R-R-0271	BSA-Mannan Oligosaccharide	BSA-Mannan oligosaccharide refers to a complex formed by conjugating bovine serum albumin (BSA) with mannan oligosaccharides.The conjugation of BSA with mannan oligosaccharides results in the formation of a BSA-Mannan oligosaccharide complex. This complex can be used in several applications, particularly in immunological studies and research. BSA serves as a carrier protein, allowing the mannan oligosaccharides to be presented to the immune system, triggering specific immune responses.	price>
R-R-0276	Recombinant Streptavidin3, r-SA3	Recombinant Streptavidin3, r-SA3 is commonly utilized in biotin-mediated detection and immobilization systems. Its high affinity for biotin enables the capture and detection of biotin-labeled molecules or structures in various experimental setups, including enzyme-linked immunosorbent assays (ELISAs) and protein detection methods. It can be used as a tool to visualize, quantify, or isolate biotinylated targets.	price>
