A simple design and an intuitive interface make the Escali a breeze to operate. It has two buttons: one to turn the unit off or on and to tare, and another to switch the unit of measure between grams, ounces, and pounds plus ounces. According to our experts, the Escali has the ideal capacity for home and pro use: It’s capable of weighing ingredients between 1 gram and 5,000 grams (about 11 pounds). This model doesn’t beep when operating, unlike our top pick in previous years, the Jennings CJ4000 , which beeps each time you press a button. The Escali is available in a variety of colors, too (nine in all).
The HPV major capsid protein, L1, can spontaneously self-assemble into virus-like particles (VLPs) that resemble authentic HPV virions . Gardasil contains recombinant VLPs assembled from the L1 proteins of HPV types 6, 11, 16 and 18. Since VLPs lack the viral DNA , they cannot induce cancer. They do, however, trigger an antibody response that protects vaccine recipients from becoming infected with the HPV types represented in the vaccine. The L1 proteins are produced by separate fermentations in recombinant Saccharomyces cerevisiae and self-assembled into VLPs.
