FAQ

Those who are looking for an answer to the question «How can transgenic spider-goats be used to produce spider silk?» often ask the following questions:

💄 How do goats produce spider silk?

Spider silk is one of the strongest materials in nature… “We genetically engineered the goats so that they produced a spider protein in their milk. We then purify that protein from the milk and spin it into fibers,” Lewis told CNN in an interview.

💄 How can goats produce spider silk proteins?

  • The goats were bred with two spider genes to produce two key proteins used to make spider silk. Those proteins are then harvested through the goat's milk. Lewis is trying to find commercial applications for spider silk, which is stronger than steel and more flexible.

💄 How do goats produce spider silk leaves?

In 2015, they provided a $1 million contract to Utah State University to produce the silk from spider-goat. The textiles woven for this silk is lighter than Kevlar. Also, unlike nylon, it doesn’t melt, which makes it an attractive material for body armor.

In the case of the spider-goats, it is the introduction of the spider dragline silk gene into a goat. So far, there are three methods of producing transgenic animals, which are DNA microinjection, retrovirus-mediated gene transfer and embryonic stem cell-mediated transfer. The method used to make the transgenic spider-goats is DNA microinjection.

Nexia had already managed to implant the genetic material of a common garden spider onto a cell from a Nigerian goat, then cloned that cell to produce a handful of grown-up goats. Because the...

There are three benefits to using transgenic goats to produce spider silk. The first one is that just by using the transgenic goats, stronger and more elastic materials than ever before can be produced. These materials include those in the industries of medicine, military, sports and automotive.

DNA microinjection is the method used to make transgenic goats that produce spider silk. This technique successfully produces transgenic goats because introduced DNA from the spider integrates into the germs line and is passed along to every cell in the goat's body. The principles first used in 1981 are still used today with no major changes.

For instance, of seven goat kids born in February 2010, three have tested positive for having the silk protein gene. When these transgenic goats have kids and start lactating, the researchers will...

The principle of the production of transgenic animals is the introduction of a foreign gene into an animal There are three methods of producing transgenic animals which are DNA microinjection, retrovirus-mediated gene transfer and embryonic stem cell-mediated gene transfer

To produce transgenic animals, Nexia removes the silk gene from the spider's DNA and transfers it to the mammary glands of its BELE goats, an acronym that stands for breed early, lactate early.

But, the elasticity is the same as the original spider silk. The silk produced by the spider-goats has been used to create various objects, but the most innovative one is bullet-proof skin. Even though the skin is not as impregnable as a Type-1 bullet-proof vest, but it can stop a bullet fired at a reduced speed.

Spider silk has generated lots of interest because they are stronger than almost any other manmade fiber. It is stronger than steel and more elastic than a rubber band. Because of that, s pider silk has sparked dozens of ideas of new and innovative ways of how to use it but nobody has had a sufficient amount of spider silk material to conduct full scale tests of these would-be products.
