WebThe biotin-streptavidin bond is broken by harsh conditions. • Incubate beads in 10 mM EDTA, pH 8.2 with 95% formamide at 65°C for 5 min, or 90°C for 2 min. >96% of … WebStreptavidin is a homotetrameric protein, isolated from Streptomyces avidinii, which, like avidin, has a high affinity for biotin. Streptavidin is slightly anionic (pI ~ 5-6) and non-glycosylated. These properties contribute to its relatively low non-specific binding compared to egg white avidin. Streptavidin is also more resistant than avidin ...
