Logo needed for antibody sales company

The name of the company is Nexus Biologicals. Need a logo that:
a) conveys the idea that our reagents (antibodies) will allow the user make "connections" (the definition of Nexus) in their research if they use our reagents;

or

b) Antibodies are proteins that are made in rabbits which are valuable reagents for many biomedical research. Need a logo with a picture of a rabbit. I'm not looking for image of a fuzzy, cute rabbit in the logo, but something that is proper. This company (http://www.bethyl.com) sells the same reagents as what we will be marketing and I like how they make use of the 3 animals in their logo. If you incorporate an animal in the design, please make the image of the animal dignified.

Nexus Biologicals

Our company sell antibodies, which are very important reagents that are used for biomedical research by scientists in universities and biotech companies. I'm looking for a logo that conveys the message that our reagents (antibodies) will allow the user to make "scientific connections or discoveries" if they use our reagent. The definition of Nexus is a means of connection or link.

An alternative will be to incorporate an image of a rabbit with the name of the company, but please do not make the rabbit look like Bugs Bunny or anything cartoonish.

Also, the shape of an antibody is like the letter "Y" . A logo that incorporates this idea is also welcome. This antibody company's logo makes use of this theme: http://www.abcam.com
