Demonstrate amoeba structure, locomotion, and feeding behavior.

Spirogyra is a genus of filamentous green algae with chloroplasts arranged in a helical (spiral) pattern.

Freshwater. Colonial; net-like structure with multinucleated cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Ascomycete. Baker’s yeast. Reproduction by budding. Incubation temperature 30°C. YM agar growth medium.

All of our most popular crosses, already done for you. We'll do all the pre-work, so you can spend more time with your students.

One of the largest Drosophila species. Useful for preparing salivary gland chromosome squashes.

Mature Drosophila are cultured in our own labs, and are marked with the culture initiation date. Culture is shipped in our instant medium in a shatterproof vial. The Fruit Fly pupae will usually appear within ten days of the ship date. You will also receive WARD’S Drosophila Culture Guide. Note: We can supply any of our single strains in the larger quantity for 100 students. Call our Customer Service department for details.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

The presence of A. viscolactis in milk is a common cause for sliminess or "ropiness".

This yellow, shiny organism is known to cause wound infections and more famously, toxic shock syndrome.

Zygomycete. Dung Mold. Mating strain; cross with Mucor heimalis (-) for zygospore formation. Incubation temperature 25°C. Potato dextrose agar growth medium

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.
