What is the order of ALP isoenzyme electrophoresis migration from slowest to fastest?

The order of alkaline phosphatase (ALP) isoenzyme electrophoresis migration from slowest to fastest is accurately represented in the provided option.

To understand this order, it is essential to recognize the different tissue sources of ALP and how their varying molecular weights and structures affect their electrophoretic mobility. ALP isoenzymes originate from various tissues, including the liver, bone, placenta, renal, and intestine, each possessing unique properties.

The renal isoenzyme has the lowest mobility due to its larger size and structural characteristics, which results in slower migration through the gel matrix during electrophoresis. Following the renal isoenzyme, the intestinal isoenzyme migrates slightly faster, accompanied by the bone isoenzyme, which also moves at a moderate pace. Next in the order is the placental isoenzyme, which migrates more quickly than the previously mentioned isoenzymes. Finally, the liver isoenzyme, being the most mobile and smallest in size, migrates the fastest.

This sequential order of migration reflects their respective physicochemical properties when subjected to electrophoresis, underscoring their varied release profiles from different tissues under physiological and pathological states. The understanding of this migration pattern is essential for interpreting ALP isoenzyme results in clinical contexts.
