Definitions
- This invention relates to a composition and to a method of using that composition for the determination of albumin in body fluids such as urine, for example.
- Hellers test which involves placing an amount of concentrated nitric acid in a test tube and stratifying a small amount of urine on the nitric acid. A cloudy ring at the junction of the two liquids indicates a positive specimen.
- Picric acid test which involves placing a measured amount of urine in a test tube and adding an equal amount of saturated picric acid solution. Turbidity of the solution indicates a positive specimen.
- albumin is precipitated either as a ring at the junction of the specimen and the precipitating agent, or as a suspension wherein the specimen is thoroughly mixed with the precipitating reagent.
- composition and method for albumin determinations that is unique in its ease of application.
- the nature of the composition and method of use is such that an unskilled person can conduct the test and can, moreover, readily run mass screening test determination on large groups of urine specimens.
- compositions of that tablet in general includes a protein precipitant comprising a member of one or more of the following groups: (1) a strong, solid, water-soluble acid such as suliosalicylic acid or picric acid, (2) the alkali metal phosphates as are particularly represented by sodium tetrametaphosphate or sodium hexametaphosphate, and (3) metal salts such as lead nitrate, zinc sulfate, barium chloride, aluminum sulfate or aluminum chloride.
- a second ingredient of the present composition comprises, an eliervescent couple consisting of a strong, solid, water-soluble acid such as those listed above as protein prccipitants or maleic, tartaric,
- the third primary ingredient is a dye component consisting of one or a plurality of dyes at least one of which has an atlinity for the protein as precipitated from solution to the extent that it is adsorbed upon the precipitated protein.
- one or more of the dyes constituting the dye component must exhibit a color change from its acid to its basic color within the range of pH increase which the precipitated albumin uniquely exhibits.
- Example IX In all of the foregoing examples, precipitation or" the protein was effected below its iso-electrie point.
- sulfosalicylic acid, picric acid, sodium tetrametaphosphate and sodium hexametaphosphate are examples of chemicals which will precipitate protein below the isoeleetric point, the sodium tetrametaphosphate and hexametaphosphate requiring additional acidity such as is provided by sulfamic or citric acids, for example.
- the reactant mixture should be at a pH no higher than 3 and consequently the dye component must change from the acidic color to the basic color at or below a pH of 3.
- the optimum pH for the precipitation appears to be in the range of 2.0 to 2.5.
- Dyes which possess these desirable or essena color difference inasmuch as a pH of 6 seems to be the tia-l attributes are Brilliant Green (sulfate salt of tetrahighest pH at which the method and composition will ethyldiaminotriphenylmethane), Crystal Violet (hexa- Work when the protein is precipitated above its iso-elecmethylpararosaniline chloride), Cresol Red (o-cresolsu ltric point.
- Metanil Yellow ' (monosodium salt of 4-m- I sulfophenylazodiphenylaniine) and Basic Fuchsine (a Citric acid 5 3-7 mixture of rosaniline and pararosaniline hydrochlorides)
- l-fig are examples of dyes that are suitably adsorbed upon the Sodium bicarbonate. 3 2-5 Sodium citrate 14 11-18 precipitated protein but which give a more difficultly determinable result because of their weak tinctorial effect.
- Example IX the sulfosalicylic acid and the sodium hexametaphosphate, both separately and together, precipitate the protein, the acid providing sufilcient acidity for Q lhhthasthig P i Point hlghhl' thal ⁇ that of t the hexametaphosphate to function.
- Calcium sulfate is used as a n and bm-ic acid as a lubricant to aid tabletting' vescence at the tablet surface, the precipitated protein For precipitating albumin above its iso-electric point, 40 cohl-ehttated and isolated on p of the l P- we have found that lead nitrate, Zinc sulfate, barium chlo- Patehtly, tit the momhht of its P P the albumin ride, aluminum sulfate and aluminum chloride exemp ify P Suthvieht Carbon thOXtdc to cause the albumin the water-sol-ublesalts of metals that willfunction in'this to fish to the Surface and remain conversely in role.
- Yellow No. 1 the color changes from violet to yellow.
- the change will be from its acid color to its basic color in positive specimens within the capacity and range of pH increase effected by the ggg g g -g g g g g precipitated protein as has been earlier discussed.
- a method for the determination of albumin in The foregoing are illustrative examples using Bromcresol Green (tetrabromo m cresolsulfon -phthalein), liquid on a tableted mixture of a protein precipitant, a Resazurin (Diazoresorcinol), Lacmoid (heptahydroxy- 7 dye having an affinity for the precipitated protein and a liquid which comprises depositing a test portion of the which exhibits a color-change Within the variation of pH effected by the precipitated protein, and an effervescent couple effective When moistened by said liquid to release carbon dioxide, said carbon dioxide forming with said liquid a foam on the surface of said tablet, said foam including the dyed albumin precipitated from said liquid.
- a method for determining albumin in a liquid the step which comprises precipitating albumin from said liquid by depositing a test portion of the liquid on a tablet comprising a mixture of a protein precipitant, a dye having an aflinity for the precipitated protein and which exhibits a color change Within the variation of pH effected by the precipitated protein, and an effervescent couple eifective when moistened by said liquid to release carbon dioxide, whereby said carbon dioxide forms a foam with said liquid on the surface of said tablet, said foam including dyed precipitated albumin.
- a composition for determining the presence of albumin in liquids comprising a tableted mixture of a protein precipitant selected from the group of metal salts consisting of lead nitrate, zinc sulfate, barium chloride, aluminum sulfate and aluminum chloride, a dye having an afiinity for the precipitated protein, said dye exhib-it ing a color change within the range of pH increase effected by such precipitated protein, and an eflervescent couple consistin essentially of a strong Water-soluble onganic acid and a member of the group consisting of alkali metal carbonates and bicarbonates.
- a protein precipitant selected from the group of metal salts consisting of lead nitrate, zinc sulfate, barium chloride, aluminum sulfate and aluminum chloride
- a dye having an afiinity for the precipitated protein said dye exhib-it ing a color change within the range of pH increase effected by such precipitated protein
