Four to six adults of each sex (including virgin females) have been carefully selected for the parent generation. Larvae will be visible within a week of receipt. Please order 7-10 days in advance.

We fully guarantee the purity and viability of our Drosophila melanogaster cultures. A large, vigorous culture is shipped in a shatterproof plastic vial. To ship Drosophila cultures with living larvae we require 10 days' notice prior to use date. During very cold weather, adult flies may die but eggs and larvae usually survive. Allow cultures to come to room temperature before checking under low magnification for eggs and live larvae. Complete instructions are always included.

Ideal for comparative study, the four cultures included in this set represent green algae's variety of physical morphologies.

Yeast strains are ideal for genetic study because they are easy to grow and maintain, their life cycle is complete in approximately one week, and you can arrest different stages of the life cycle by growing it on different types of media.

Two strains of Escherichia coli (donor and host) with complementary sensitivities to Ampicillin and Streptomycin. Watch them trade traits via conjugation.

Learn genetics like Mendel.

Ames test strain for detecting carcinogens. Causes infection in humans.
