Quantitative detection of PML-RARalpha fusion transcript by real-time PCR with a single primer pair.

Quantitative detection of minimal residual disease has prognostic value for some leukemias. Acute promyelocytic leukemia (APL) is characterized by the specific PML-RARalpha fusion gene from t(15;17). Added to three PML-RARalpha isoforms, alternative spliced forms of PML exons give rise to multiple isoforms even within a single patient.

Assessment of allergenic activity of a heat-coagulated ovalbumin after in vivo digestion.

We often eat heat-coagulated (H-C) food proteins, but there have been few studies on the allergenic activity of H-C proteins after digestion and absorption in vivo. To show that H-C protein is not an allergen after digestion, mice were used to investigate the digestion and absorption of the protein through the intestinal epithelium into portal blood employing immunoblotting and competitive inhibition ELISA. Ovalbumin (OVA) was used as the model protein, and H-C OVA was prepared by heating a 5% OVA solution for 15 min in boiling water.
