From Minecraft Wiki. The purpose of an enderman trap (popularly called Ender Ender) is for the easy access and killing of endermen. It is possible for the user to create such a trap that can be used by simply standing still, and looking at the endermen. This angers any you look at, luring them into the trap.he purpose of an enderman trap (popularly called Ender Ender) is for the easy access and killing of endermen.

Causes of Cross-Contamination - how it happens (continued): â¢Processing excessive number of specimens in one batch due to staff shortages may lead to breakdown in protocol adherence and introduce potential error for cross-contamination.
We have found that the best way to minimize cross-contamination is to designate specific areas for specific practices. In our main lab we culture the bacteria, in an ancillary lab we propagate the phage, and then we have another lab where we do all our molecular work such as PCR.
