Researchers discover new enzymes for universal Type “O” blood

 

The  University of British Columbia (UBC) researchers have discovered a new, more powerful group of enzymes that could turn any type of blood into the universal Type “O ”blood.

The recent breakthrough, announced in a news release by the university, is expected to eventually expand the pool of potential blood donors and make blood matching safer and easier.

Blood type is determined by the presence of antigens on the surface of red blood cells.

Type A blood has the “A” antigen, “B” has the “B” antigen, “AB” blood has both antigens and “O” blood has none.

Antigens can trigger an immune response if they are foreign to the body, so transfusion patients should receive either their own blood type, or Type “O” to avoid a reaction.

Researchers have been studying the use of enzymes to modify blood for nearly 40 years.

However, these new enzymes can do the job 30 times better, leading researcher Stephen Withers, a professor of chemistry at UBC, said.

Withers and his team focused on the mucosal lining of the human gut, which contains sugars that are similar in structure to blood antigens.

“By honing in on the bacteria feeding on those sugars, we isolated the enzymes the bacteria use to pluck off the sugar molecules.

“We then produced quantities of those enzymes through cloning and found that they were capable of performing a similar action on blood antigens,” he said in the news release

The team is now applying for a patent on the new enzymes and hoping to test them on a larger scale.

According to him, the next step is to hold tests to show that the blood behaves properly once converted, if that works well human clinical trials could start within the next two years.

I am currently a procurement officer and the salary is really rewarding. Vermont is where my home is and my parents live nearby. You can find my website here: #link#

  6. This is the right blog for anyone who wants to find out about this topic. You realize so much its almost hard to argue with you (not that I actually would want?HaHa). You definitely put a new spin on a topic thats been written about for years. Great stuff, just great!

  7. I just want to say I am very new to weblog and truly liked this blog. Likely I’m planning to bookmark your site . You really have great stories. Appreciate it for sharing your web-site.

  8. Nice post. I learn something more challenging on different blogs everyday. It will always be stimulating to read content from other writers and practice a little something from their store. I?d prefer to use some with the content on my blog whether you don?t mind. Natually I?ll give you a link on your web blog. Thanks for sharing.

  9. This design is incredible! You obviously know how to keep a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!) Excellent job. I really enjoyed what you had to say, and more than that, how you presented it. Too cool!|

  10. I simply want to say I am just beginner to weblog and definitely enjoyed your page. Probably I’m going to bookmark your blog post . You actually come with awesome articles and reviews. With thanks for sharing your website.

  11. This is the right blog for anyone who wants to find out about this topic. You realize so much its almost hard to argue with you (not that I actually would want?HaHa). You definitely put a new spin on a topic thats been written about for years. Great stuff, just great!

  12. I think that everything wrote made a great deal of sense. However, what about this? what if you added a little content? I mean, I don’t want to tell you how to run your website, however suppose you added something to maybe grab a person’s attention? I mean BLOG_TITLE is a little vanilla. You should peek at Yahoo’s home page and note how they create article titles to get viewers to click. You might try adding a video or a related pic or two to get readers excited about everything’ve written. In my opinion, it might make your website a little bit more interesting.|

  13. Thanks for finally writing about > blog_title < Loved it!|
