For measurement of amylose and starch content, unhusked brown rice kernels were polished to remove the embryo and pericarp with a test mill (Pearlest; Kett Electric Laboratory, Tokyo, Japan), after which these kernels were ground into powder with a food mill (Milser, IFM-800DG, Iwatani Corporation, Tokyo, Japan).
Remove the embryo from the nucleopore filter just prior to placing in 100% ethanol during the prehybridization step.
Scientists remove the embryo-to-be's genome, also called nuclear DNA.
To verify that abnormal Bcd during cycles 11 13 in bcd-eGFP embryos can give rise to normal patterning during cycle 14 to gastrulation, we imaged a bcd-eGFP embryo using the same protocol as embryos shown in Figure 3, removed the embryo from the microfluidic device, and immunostained the embryo for Eve expression.
The method involves removing the embryo from the yolk and culturing it on a glass ring in albumen.
After removing the embryo (one tissue), the endosperm was squeezed out (second tissue) and the remaining maternal tissue formed the third tissue that was collected.
The red organs were removed, the embryo was minced and resuspended in 1 ml trypsin and incubated at 37°C for 15 min before the addition of 10 ml growth medium.
After removing the embryos, polished seeds were dried overnight, weighed, digested, and then analyzed as described above.
The yolk was manually removed, the embryos permeabilized for one hour with PBS/1% Triton X-100 and then blocked for two hours in PBS/4% BSA/0.3% Triton X-100 at room temperature.
The vitelline membrane was removed, the embryos were isolated with intact area opaca and pellucida and fixed overnight (o/n) at 4°C either in 4% paraformaldehyde (PFA) for whole mount immunofluorescence or in Bouin's solution (Sigma) for immunohistochemistry and stored in PBS at 4°C until further use.
To be on safe legal ground, Guenin and others say, Congress needs to remove the prohibition against embryo research or pass a law explicitly allowing federal funding of research on hESCs.
