Recombinant DNA: Recombinant DNA (rDNA) molecules are DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) to bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome. https://en.wikipedia.org/wiki/Recombinant_DNA ...Read moreSee 1 more doctor answer
Cut & splice: Its my understanding that they can produce the code for creating the protein component of a germs cell wall & insert it into the dna of a common bacteria. They grow the bacteria in nutrient rich vats & the bacteria produce the protein in excess & expel it into the vat.That protein can be purified & becomes the basis of a vaccine. Neat technology that has cut down the frequency of vaccine reactions. ...Read more
No: You can use both but need separate injections. ...Read more
SIGNIFICANCE???: Hi. Not to be disrespectful, but what do you MEAN what's the significance??? Animal insulins are no longer even available in the US. Every type 1 you know and half the type 2's are alive and managed because of recombinant (and in the vast majority of cases, engineered) insulins. Significance? How about ALIVE!? ...Read more
Ultra High Tech!: These products(which are used to treat a wide variety of bleeding disorders like hemophilia, and von willebrand's disease) are made either by being completely free of human plasma derivative; or use a pasteurized form that is very safe. These products are not without there share of risks; and can potentially cause diseases as well. They are also very, very expensive so let the buyer beware! ...Read moreSee 1 more doctor answer
Could you tell me what is the significance of recombinant insulin in history of biotechnology development?
Old vs new technolog: The whole cell pertussis,an early vaccine,was basically dead germs that were broken into pieces and given. This gave great protection, but almost all infants had high fevers by the 2nd or 3rd dose, and it could never be giver after age 6. Today's pertussis is a synthetic replica of part of the germ. Its "clean" origin produces almost no side effects and the vaccine can be given at any age ...Read more
What are the differences between recombinant tissue plasminogen activator and tissue plasminogen activator?
Same aa sequence: tPA and its recombinant version (Activase) are identical with respect to the amino acid sequence. There have been reported some minor differences with respect to glycosylation of the protein, but this is well within the specifications of the cGMP production by the manufacturer. ...Read more
Hepatitis c (HCV) antibody is reactive. The hepatitis C Recombinant Immunoblat Assay(riba) confirmation test is non reactive.Is antibody false positiv
Well : A positive hepatitis C antibody test with a negative or in a test usually is not a false positive that usually means someone had hepatitis C infection and their body cleared the infection and they are now immune to hepatitis C. Do a Healthtap visit or see a primary care physician for specific diagnosis ...Read moreSee 1 more doctor answer
With new advance technology. What's the most superior way to detect all ID's and Toxins? Protein? or Antibody or Antigen? This is better then DNA?
No single answer: This varies tremendously depending on the possible infectious agent. The speed of the test, the sensitivity, the specificity and the cost are all factors. Anyone offering a simplistic answer is someone without real-life experience here. ...Read more
