     Because immunotactoids may be composed of either immune complexes or monoclonal proteins, which are capable of forming tactoids or microtubules, the variability in the size and the orientation of the tactoids from one patient to another may be a result of concentration or biochemical composition of the protein similar to that described in cryoglobulinemia.

     Minute quantities of chiral molecules such as amino acid L-alanine and limonene transform the racemic array of left- and right-twisted tactoids into a homochiral set.
