Surface Layer Protein for Nanotechnology
125Kd S-Layer Protein has been purified in ProteinX Lab. It forms
a homogeneous dimmer in PBS. Sample is more than 95% pure. We are looking
for a strategic collaboration on Nanotechnology by using S-layer protein,
please contact us with your specific question. If you prefer to purchase
it, please use the Cat. No. below. This protein has been supplied
to the researchers in UCLA, UT(Austin) and IBM (Well,
maybe your next lovely Thinkpad is edible, so watch out your pet).

It is a 2D platform, here
is a 3D nanoscale building platform from ProteinX Lab-- HBV core particles(T=4)
Designing nano-structure? then
look at the master piece of Nature--HK97 particles(T=7)

S-layer
proteins as nano-building blocks
Why S-layer protein?
Proteins are the master piece of Nature, they can
be divided into two categories, structural protein and functional protein.
Structural protein is to support the life, relatively simple (you
can call them "nano-buiding blocks"); functional protein is to carry out
life, generally more delicate (they are real "nanomachines"). S-layer proteins
belong to structural protein. Other interesting structural proteins may
include virus coat proteins, cell skeleton proteins.
There are a couple of reasons that make
S-layer protein are favorite nano materials compared to so-called carbon
structures.
1. Biodegradable
Do we need say anything about this?
And, it may be not too late to remind those
"nano guys" of old chinese saying, "you pay the price if you offend the
Nature". Please do not destroy our beautiful planet by your non degradable
nano-particles.
2. Nano manufacturing facility is available
50 years after discovery of DNA structure,
it is known how proteins are made. Thus, it is possible for us to
take advantage of the nano production line Nature provides
us to make nano-building block and nanomachines. Here, what you need to
do is to give it your blueprints (recombinant DNA), sit down, and
relax.
3. Self-assemblable nano building blocks for bottem-up
One of the remarkable features of structural
protein is that they can self-assemble into predefined structure, and this
assembly process is controllable (so-called assembly pathway).
4. Protein has more to offer than carbon structure
Basically, proteins have C-N backbone, however, the side
chain is made of other elements, including, but not limited, C, H, S, N,
O, P. Artificial proteins can have other elements.
Understanding the rigidity and the flexibility of protein structure
is still the frontier of protein assembly research.
