strep·ta·vi·din

(strep'ta-vī'din),
A bacterial protein used as a probe in immunologic assays because of its strong affinity and specificity for biotin; streptavidin is used as a bridge to link a chromogen to a biotinylated substrate specific for the substance of interest.

streptavidin

[strep′təvī′din]
a biotin-binding protein isolated from Streptomyces and used to identify antigens; a widely used reagent for immunoassays.

After incubation of the samples in a dark room for 30 min at 25 [degrees]C, 50 pi of streptavidine PE solution was added into each well.
Alternatively antibody HLA-monomer complexes were made by incubating biotinylated CD89 or MR with biotinylated HLA-A2 monomer and APC-labeled streptavidine (at a ratio of 2 : 2 : 1, resp.
To establish that entry of the complex was mediated via CD89 we generated a complex of "APC-labeled streptavidine, biotinylated CD89, and biotinylated HLA-A2" (CD89-A2-strep).
g) Uptake was confirmed by formation of a complex with biotinylated-CD89 and HLA-A2 monomer incubated with APC-labeled streptavidine (CD89-A2-strep) at a ratio of 2: 2: 1, respectively.
