Description

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[1]. Streptavidin has an immunosuppressive role[2].
This product is a Streptavidin protein recombinantly expressed in an E. coli expression system.

In Vitro

Streptavidin (2-200 μg/mL) significantly suppresses the proliferation of Lewis T cells to WF by 76%-83% compared with untreated responders[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: Lewis T cells
Concentration: 2-200 μg/mL
Incubation Time:
Result: Inhibited the proliferation of Lewis T cells to WF stimulators by 76%-83% compared with untreated responders, lower concentrations of 0.1 and 0.2 μg/mL did not significantly inhibit T-cell proliferation.
In Vivo

Streptavidin (8-80 mg/kg) treatment is effective in prolonging rat cardiac allografts in the high-responder WF-to-Lewis combination[2].

Animal Model: Lewis rats[2]
Dosage: 8, 12, 20, 40, 60, or 80 mg/kg
Administration: Administered IP for 5 consecutive days after transplantation was combined with a single dose of 0.5 mL antilymphocyte serum (ALS) on day 0
