WebThe major factors that contribute to high solute concentration into the renal medulla are: 1. Active transport of sodium ions and cotransport of potassium chloride out of the thick ascending limb of LOH into medullary interstitium. 2. Active transport of ions from the collecting ducts into the medullary interstitium. ADVERTISEMENTS: 3. WebWith most protein assays, sample protein concentrations are determined by comparing their assay responses to that of a dilution-series of standards whose concentrations are known. Protein samples and standards are processed in the same manner by mixing them with assay reagent and using a spectrophotometer to measure the absorbances.
