20120264199 | PREPARATION METHOD OF THE COMPOUNDS FOR ABSORBING HEAVY METALS - The present invention is related to a preparation method of the compounds for absorbing heavy metals. First of all, prepare natural vegetable or fruit and extract a B-M sulfur peptide from the said natural vegetable or fruit. Second, place the natural vegetable or fruit into fermentation and extract the mixed nutrient extraction. And then mix the B-M sulfur peptide and the mixed nutrient extraction as the final extraction. Mix the final extraction into drinks. The final extraction will slowly release B-M sulfur peptide when entering the body; through its combination of heavy metals and re-absorption by the body, useful materials are retained in the human body while long-term accumulated toxic metals are discharged to repair the body's metabolism. | 10-18-2012 |
20130164827 | PROTEIN SEPARATION VIA ION-EXCHANGE CHROMATOGRAPHY AND ASSOCIATED METHODS, SYSTEMS, AND DEVICES - The present invention provides methods for separating proteins from a protein mixture. In one aspect, a method for separating a high concentration protein mixture into a bound protein fraction and a flow-through protein fraction can include delivering a protein mixture through an ion exchange column at a fixed pH and a fixed salt concentration. The fixed pH and the fixed salt concentration have been preselected to cause separation of the protein mixture into a bound protein fraction and a flow-through protein fraction. In this case, the bound protein fraction binds to the ion exchange column and the flow-though protein fraction flows though the ion exchange column. The method can further include receiving the flow-through protein fraction from the ion exchange column separate from the bound protein fraction, wherein either the bound protein fraction or the flow-through fraction contains a protein of interest. | 06-27-2013 |
