Abstract:
... A feeding trial was conducted for nine weeks to investigate the effects of partially replacing Ca(H₂PO₄)₂ with neutral phytase on the growth performance, phosphorus utilization, nutrient digestibility, serum biochemical parameters, bone and carcass mineral composition, and digestive-enzyme-specific activity in crucian carp (Carassius auratus). The diets prepared with 0.8%, 0%, and 1.8% Ca(H₂PO₄)₂ ...

Subject:
antigens; colorimetry; enzyme-linked immunosorbent assay; magnetism; researchers
Abstract:
... Immunomagnetic bead (IMB)-based enzyme-linked immunosorbent assay (ELISA) has been the tool frequently used for protein detection in research and clinical laboratories. For most ELISA reactions the recommended dosage of IMBs is usually according to their weight (mg) or mass fraction (w/v) instead of the bead number. Consequently, the processes occurring in the immediate vicinity of the IMBs have a ...
