In the experiment there are three players A, B, and C. Player A gets an initial endowment of 10, player B gets 0 and player C gets 5 points. First, player A decides how many of his 10 points to transfer to B. Then, player C observes the decisions of A and gets the possibility to leave the payoffs unaffected or to punish A by deducting 3 (or 6) points from A at a cost of 1 point (or 2 points) for C.... - [Read Experiments on Parochial Altruism in Humans; Procedures and Instructions]

This protocol contains methods for pulling microinjection needles using two different models of pipette pullers. The advantage of pulling needles in the laboratory is that a variety of different needle types can be pulled, depending on the samples and cells being injected. An added advantage is cost; once a pipette puller has been purchased, boxes of glass capillaries are inexpensive compared to premade microinjection needles. - [Read Preparation (Pulling) of Needles for Gene Delivery by Microinjection Protocol]

This protocol describes a method for testing of new serum lots prior to use in cell culture. Serum lots vary considerably in their ability to support cell growth, and some lots even contain toxic or growth-inhibitory compounds. It is advantageous to test serum lots and purchase in large volume, both for cost benefit. - [Read Serum Testing for Mammalian Cell Culture Protocol]
