We report here straightforward methodology for the purification of chemically synthesized proteins which are produced in low yield. The methodology is generally applicable to all proteins still on-resin and fully protected except for the terminal amino group. The protein is treated in order with the following steps: Biotinylation with NHS-biotin, HF cleavage, and avidin-agarose affinity chromatography. No special skills or automated equipment are needed to take advantage of this procedure.
