What is insulin made by?

Answer 1

Insulin is made in the pancreas. It helps to control the concentration of sugar in your blood. People who suffer from Diabetes arent able to make enough insulin, therefore they inject it to control their blood sugar. x

Answer 2

The vast majority of insulin used to treat diabetes is actually not produced in a lab. It is harvested from pigs, which share a surprisingly large about of DNA with humans.
Bacteria have a gene for producing human insulin added, and then they are grown and produce the insulin.

Answer 3

Insulin was until recently made by cultivating pancreas tissue from Cow, Pig and even Fish.

The insulin one got from these were slightly different from human insulin, but they do work as they intend to in humans.

It is and was considered time consuming and difficult to produce in sufficient purity and quantity and researchers started testing other methods.

Scientists have isolated the gene that starts the production of insulin. By inserting this gene in other organisms we can trick them into producing it for us.

The gene have been put into fungus and bacterias and it works very well.

In 2007 the scientists managed to put the gene into an actual plant. The plant grows well and produces large amounts of insulin. Something that makes this the most cost effective method of producing insulin today.

Scientist produce several different types of insulin these days. Humans have a sort of "slow" acting insulin and this is not always the best choice for a person with diabetes.

Fast absorbing insulin is often a better choice. It is not the same as human insulin but it does the job it is supposed to do.

I will at the end just point out that:

The insulin itself is not genetically engineered.

We have genetically engineered plants and bacteria and fungus to produce the insulin for us.

Answer 4

Best successfully purified insulin, from a dog's pancreas. In 1936, researchers came up with a way, to make insulin with a slower release in the blood. They added a protein found in fish sperm, protactinium, which the body is able to break down slowly. One injection lasted for 36 hours. In the 1970s, researchers began to try and produce an insulin that had more resemblance to the body's natural insulin.

Answer 5

Regular insulin is made of sterile aqueous neutral solution of insulin. It is now made from purified crystalline zinc insulin. Its vehicle is glycerin which serves as a colsolvent and stabilizer plus phenol or cresol as preservatives.
