A Proteomic Style Approach To Characterize a Grass Mix Product Reveals Potential Immunotherapeutic Benefit

Background Grass allergy immunotherapies often consist of a mix of different grass extracts, each containing several proteins of different physiochemical properties; however, the subtle contributions of each protein are difficult to elucidate. This study aimed to identify and characterize the group 1 and 5 allergens in a 13 grass extract and to standardize the extraction method.
