Since hydroxyapatite binds IgM strongly at physiological pH, conductivity, mild, non-denaturing conditions can be used for elution.
Association between DAT positivity along with elution positivity and high bilirubin levels was assessed using chi-square test.
Using the optimized derivatizing conditions, the repeatability of the GC elution was examined (n=5) and relative standard deviation (RSD) was observed within 0.
High pH and salt levels were needed for complete protein elution, indicating that charge-charge interaction was involved in association of these proteins with Nuvia cPrime Resin.
In this initial international study, subjects were randomized to receive either one of two models of the implant, each with different elution rates, or topical travoprost.
From an operational viewpoint, neither special equipment nor sophisticated skills are required, because the simplest elution mode, isocratic elution, is applied throughout chromatographic run.

We found that 10 mM of imidazole and 500 mM of NaCl in the washing solution are the optimal concentrations for HSC70 purification, and we detected a single clear band in the elution indicating the exclusive presence of HSC70 using the optimal concentration of imidazole and NaC1 (Figure 4A and 4B).
About one decade later the absorption elution technique was substituted for Absorption inhibition technique and is most exclusively used for this purpose in forensic laboratories.
In our view, improving the effectiveness of RhIg dosing would require 2 things: (1) a more accurate calculation of maternal blood volume, such as Dr Ramsey's RhIg Dose Calculator2; and (2) replacement of acid elution FMH quantitation with flow cytometry in all cases in which additional Rh immune globulin doses are indicated by initial Rosette or acid elution test results.
