4.5 to 5.5 . its acidic.

(ka1*ka2)^(1/2)
An amino acid is considered to be at its isoelectric point when the positive charges on the molecule exactly balance its negative charges. At this point, the amino acid carries no net charge and is therefore immobile in an electric field. Isoelectric points of amino acids widely vary accoriding to their side chains and polarity characteristics.
what does isoelectric line represent
It is the pH at which a particular molecule or surface carries no net electrical charge
An isoelectric line on the electrocardiograph is the base line on an electrocardiogram.
hbsag + means that he have diseases and hbsab negative men that he dont have immunity
pI is the isoelectric point. This is a pH value where a protein has no net charge. NOTE: Proteins may have multiple pI's.
mouse
The result is that the patient HIV infected if the hbsag is negative.
