How are antibodies used for blood typing?

Ask an Expert Topic Forum: Grades K-5: Life, Earth, and Social Sciences

How are antibodies used for blood typing? How are antibodies used for blood typing? I was wondering if anybody knows the answer to this question. We are doing the experiment on how are antibodies used for blood typing. I know that my controlled variables are the antiserums, amount of drops, and the amount of time to mix the solution. So, in this experiment I don't necessarily have a controlled group because the things that I'm not changing are the antiserums, drops, and time. The only… Read more

Amazonia Microarray Database Amazonia Microarray Database Hello, I am working on a Science Buddies project that requires the use of the Amazonia microarray database, but the site is unfortunately down on my end. I saw an earlier post from a few years back mentioning that the site wasn't working for them either and a working solution was not mentioned. It seems that the site still hasn't been fixed, and I'm not exactly sure if there is another microarray tool that can help complete this… Read more

Could cancer be used as Biofuel?
