Planar static images of MDA-MB-231 tumor-bearing mice at different time period after i.v. injection of (a) ^99mTc-BN4 alone at 30 min, (b) ^99mTc-BN4 alone at 120 min, (c) ^99mTc-BN3 alone at 30 min, (d) ^99mTc-BN3 alone at 120 min, (e) ^99mTc-BNS alone at 30 min, and (f) ^99mTc-BNS alone at 120 min. (a′) ^99mTc-BN4 blocked by co-injection of BNS at 30 min. (b′) ^99mTc-BN4 blocked by co-injection of BNS at 120 min. (c′) ^99mTc-BN3 blocked by co-injection of BNS at 30 min. (d′) ^99mTc-BN3 blocked by co-injection of BNS at 120 min. (e′) ^99mTc-BNS blocked by co-injection of BNS at 30 min. (f′) ^99mTc-BNS blocked by co-injection of BNS at 120 min. Three animals were used for each group
