Blood Typing Biokit, For Class Of 30 Students, Instructions Included

Worked well and was suitable for a room of 7th graders

This is an economical way to do blood-typing for a class, even for a small class. The serum will keep in the refrigerator up to a year, so I purchase mid-year at the time of the genetics unit and do one class. Then I save it until the beginning of the following school year and do that year's class early. This provides data for students to figure out their own genotypes as well as genotypes of some family members, using other known family data. The kit is very easy to use and gives accurate results.
