Tyramine → Biotin tyramine

Participants

Reaction Steps

Para-hydroxyphenylpropionyl biocytin (HPPB) was prepared by mixing a solution of p-hydroxyphenylpropionic acid-N-hydroxysuccinimide ester (50 mg [0.2 mMol]/2 ml dimethyl sulfoxide) with biocytin (70.75 mg [0.2 mMol]/2 ml 0.1M NaHCO3) overnight at room temperature (RT). Biotin-tyramine (BT) was prepared by mixing a solution of tyramine (40 mg [0.3 mMol]/1 ml dimethyl sulfoxide) with biotin-N-hydroxysuccinimide ester (100 mg [0.3 mMol]/1 ml dimethyl sulfoxide) overnight at RT. The solutions of HPPB and BT were used as is. The calculated concentrations were 26 mg/ml for HPPB and 55 mg/ml for BT.
