-What is spider web or silk?
Researchers have been able to produce spider web automatically in vitro. It is produced outside the body of the animal, which is dramatically stronger than the silk produced by the silkworm. Silk has been used by humans for thousands of years, unlike the spider silkworm that has been domesticated by humans so that we can Use it for commercial silk production.
Scientists have applied a way to produce silk independent of the need to access the insect itself. This method relies on genetic engineering to produce a protein from which spider web is made. To do this, they used bacteria, yeast, plant cells, and mammalian cells on the skin cells, but these methods were unsuccessful in producing a natural-like web.
A team of researchers, through genetic engineering, have been able to produce spider webs from spider cell specimens. These cords had the property and resistance to natural filament produced by animals. Mass production of these cords will be possible in the future in various locations in the industry. A group is currently working on its latest production based on industrial production.
Spider webs consist of webs produced by a particular protein. To synthesize these proteins artificially, researchers from parts of the Garden Spider Gene (Large-bodied and Yellow Spider in America)
The scientific name used is the animal (Araneus diadematus). The beast has been used by researchers to make the web and they use it to make this protein. This yellow spider has various threads of this protein. One of these strings is the blur that the beast uses and this strand has greater strength and elasticity. It is six times more durable than nylon and steel. It is this blur that is used to protect the animal from falling when it is vitally important to the animal.
Basically, this strand is made of two genetically similar proteins, ADF-3 and ADF-4, which are produced in the abdominal glands of animals. In an experiment the researchers did at the lab, they were by deleting a gene from the strand and putting it on a virus that causes insects to infect it, called baculovirus.
The virus was genetically engineered and then cultured on a previously mentioned skin cell belonging to a type of caterpillar or worm. This worm in America is known among the people as an army worm!
The spider and this insect have arthropods and are genetically homogeneous in that the experiment was more successful than the previous one. So they concluded that they could use these insects to produce tar. One researcher says we have developed a method to produce more of these proteins, which is remodeled by infecting insect cells with the virus that produces the blur.
After the engineered virus infects the insect cell, the cells begin to produce protein, and the strands begin to form at once. However, unlike spiders, these lab-made filaments consisted only of ADF-4 protein, but the ADF-3 protein remained soluble, but despite its filament diameter being equal to the natural filament diameter produced by the animal and some properties. This thread, like its strength, was even superior to the opacity of the spider.
Researchers believe that the diversity of this protein is similar to what happens in nature and that it causes a variety of naturally occurring fibers. This operation is of high complexity. The ADF-4 protein appears to be able to produce fast-twitch, while the other protein is to modulate the twitch production and to prevent premature twitch production and its absence can be fatal to the animal.
They say the experiment has enabled us to discover that there are close relationships between protein sequence, structure, and function. Dr. Gett says bulk production, which is 1,000 millimeters (one micron) thick, could potentially be used to make bulletproof vests, which can also be used to make surgical threads, micro-diameter conductors, optical fiber, and fishing rods. It can even be used to design clothes in the future.
Spider Garden: This one-inch-long insect is a beautiful and harmless animal. It sleeps for days, hunts at night, and is often found in the backyard of America. At night you can sit on the balcony with a UV lamp and in the dark you can watch the fast animal activity.
