Hair conditioner the hair a positive charge and creates more hydrogen bonds among the keratin scales, giving the hair a more compact structure. Organic acids such as citric acid are usually used to maintain acidity. Hair conditioner Hair conditioner is a hair care product used to improve the feel, appearance and manageability of hair. Its main purpose is to reduce friction between strands of hair to allow easier brushing or combing, which might otherwise cause damage. Various other benefits are often advertised, such as hair repair, strengthening, or a reduction in split-ends. Conditioners are available in a wide range of forms including
Protein A due to the high purity and yield which are achieved in a easily and reliably achieved. This forms the basis for a general antibody purification "platform" which simplifies manufacturing operations and reduces the time and effort required to develop purification processes. A typical mAb purification process is shown at right. Albeit the long history of protein A chromatography for the production of antibodies, the process is still being improved today. Continuous chromatography, more precisely periodic counter-current chromatography, enormously increases the productivity of the purification step. Protein A Protein A is a 42 kDa surface protein originally found in the cell
