Cat. No.: HY-P3152
CAS No.: 9013-20-1
Streptavidin is a ~60 kDa homotetramer. Streptavidin binds four molecules of biotin with the highest affinity. The binding affinity of biotin to streptavidin is one of the highest reported for a non-covalent interaction to date, with a KD ~0.01 pM . Streptavidin has an immunosuppressive role .
This product is a Streptavidin protein recombinantly expressed in an E. coli expression system.

Maackia amurensis Lectin (MAA/MAL II)-Biotinylated is a plant lectin modified by biotin. Maackia amurensis Lectin (MAA/MAL II)-Biotinylated has the activity to recognize specific sugar structures, specifically the alpha-2, 3-linked sialic acid (HY-I0400). Maackia amurensis Lectin (MAA/MAL II)-Biotinylated has a very high affinity with avidin or streptavidin and this interaction can be used to fix it to solid surfaces or bind it to other molecules. Maackia amurensis Lectin (MAA/MAL II)-Biotinylated can be used to isolate and purify proteins or other molecules with specific sugar chain structures in affinity chromatography as well as for disease marker discovery and cancer research .

R-PE Streptavidin is a streptavidin labeled with R-Phycoerythrin (R-PE) at a concentration of 0.5 mg/mL. R-Phycoerythrin is an orange-red fluorescent probe. Streptavidin specifically binds to biotin, forming a reversible non-covalent interaction. R-PE Streptavidin is commonly used in experiments such as immunofluorescence (IF), enzyme-linked immunosorbent assay (ELISA), immunohistochemical staining (IFH), and in situ hybridization (Ex/Em=785/813 nm).

APC Streptavidin is a streptavidin labeled with Allophycocyanin (APC) (HY-D1815) at a concentration of 0.5 mg/mL. Allophycocyanin (APC Dye) is a light-harvesting protein containing a strongly coupled dimer. Streptavidin specifically binds to biotin, forming a reversible non-covalent interaction. R-PE Streptavidin is commonly used in immunofluorescence (IF), enzyme-linked immunosorbent assay (ELISA), flow cytometry, and other experiments (Ex/Em=652/662 nm).
