摘要:
A stable blood serum conjugated bilirubin reference composition characterized in that the composition possess a pH of from about 8.2 to bout 9.2 and comprises (a) a sulfhydryl compound in an amount sufficient to enhance the stability of the conjugated bilirubin and (b) a chelating agent in an amount sufficient to bind all the metals present in the blood serum moiety of the composition. This blood serum conjugated bilirubin composition when stored in a gas impervious vial under an inert atmosphere has an excellent shelf life.
摘要:
An efficacious large-scale alcohol-free plasma fractionation production process which produces a high-yielding, non-denatured, double viral-inactivated intravenous human immune gamma globulin (IgG) product. The process employs sodium citrate in two initial fractionation steps, followed by diafiltration to remove sodium citrate.
摘要:
A process for making a biological composition for use as a blood serum reference composition in diagnostic analysis. The process comprises:(a) adding calcium to citrated plasma and mixing well to form decitrated plasma;(b) adding thrombin to the decitrated plasma and mixing well to form a clot of fibrin;(c) performing at least one freeze-thaw routine on the clot to cause the fibrin to contract;(d) removing the fibrin to thereby obtain serum;(e) molecular washing and ultrafiltering the serum and thereby obtaining concentrated serum; and(f) adding to the concentrated serum at least one alkylene polyol having from 2-5 carbon atoms in an amount such that said composition's non-biological component comprises from about 40 to about 85 weight percent water and from about 15 to about 60 weight percent of said alkylene polyol.
摘要:
A calibrating fluid for automated instruments for blood cell counting and hemoglobin determination comprising a sterile solution of oxyhemoglobin or other derivative products of hemoglobin and containing latex particles.
摘要:
A process for making Solvent Detergent (SD) treatment effective against non-enveloped viruses. The process stipulates using prequalified concentrations of formaldehyde and phenol with SD treatments. In particular, serial or combined use of 100 to 10,000 parts per million of formaldehyde and/or 100 to 10,000 parts per million of phenol with an associated SD treatment process are disclosed.
摘要:
HTLV-III virus in blood or blood components is inactivated by treatment with about 0.1-5% of phenol, formaldehyde, or mixtures thereof, at a temperature of about 2.degree.-40.degree. C. for at least about 5 minutes.
摘要:
A blood biochemistry control standard for the quality control of the analytical measurement of blood biochemistry components is disclosed. The control standard comprises an aqueous suspension of red blood cells which have been stabilized by mild treatment with aldehyde and saline and then slowly equilibrated with at least one additionally incorporated non-gaseous biochemical analyte in a concentration of clinical significance.
摘要:
An improved blood serum reference composition of the type comprising blood serum having constituents of known values, characterized in that said composition further comprises a water soluble amine chloride. The water soluble amine chloride is employed to adjust the negative electrolyte balance of said reference composition without interfering with presently employed blood serum clinical assay procedures or analytical equipment used therein.
摘要:
A stable blood control standard for the quality control of the measurement of blood pH and gases in the clinical laboratory and method of making the same is disclosed. The blood control standard comprises a sealed receptacle containing specially treated red cells and a gaseous head space at least equal to about the volume of the red cells. The special treatment comprises thoroughly washing and separating the red cells from the plasma components and followed by mildly treating the cells with aldehyde and retaining the cells in a buffered solution. The special treatment also includes treating at least a portion of the red cells with carbon monoxide. The head space comprises from 0-15% CO.sub.2, 0-25% O.sub.2 and the balance N.sub.2 and/or inert gas.
摘要:
An efficacious large-scale alcohol-free plasma fractionation production process which produces a high-yielding, non-denatured, double viral-inactivated intravenous human immune gamma globulin (IgG) product. The process employs one or more salts from a group of salts comprising sodium citrate, sodium acetate, sodium gluconate, ammonium sulfate, sodium chloride, sodium sulfate and ammonium chloride in two initial fractionation steps, followed by diafiltration to remove those salts employed. A process which employs alcohol via the process of the disclosed inventive method is also disclosed.
