Labs that do a lot of Western blots often have hundreds of primary bodies but only two or three secondary antibodies. Why? I understand that secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody which directly binds to the target antigen. However, I don't undrstand why there are only two or three secondary antibodies available in the laboratory. Glad if the expert would advise.
A pathogenic bacteria has entered the body via a wound: A few hours later, antigen presenting cells (APCs) can be observed displaying antigenic fragments of the bacteria. Explain the process starting with a bacterial cell living in the body and ending with an APC displaying antigenic fragments
Bacteria have evolved numerous mechanisms to prevent the invasion of foreign viral DNA (see Bacterial Defense Mechanisms). Yet clearly some bacteria have evolved competence, the ability to take up foreign DNA from the environment. Why do bacteria take up naked DNA from the environment and yet exclude DNA from viruses?
The type specific antigen (A, B or C) of influenza viruses is found on which viral constituent? A-Nucleocapsid B-Lipid in viral envelope C-Neuraminidase D-Hemagglutinin E-Major structural protein
If you get infected with the Covid-19 virus, cellular immunity is better designed to fight virally infected cells (ie. a sick respiratory cell), then defending against free-floating/whole viral particles. Why is that?.
Based off of the concept of the COVID-19 vaccination, which of the following conditions is very similar to that same concept used to develop immunity to the COVID-19 virus?a. postinfectious arthritisb. type I diabetesc. lupusd. heart attackse. grave’s disease
each virus bind to a specific cell surface receptor for attachment, so prevention of viral attachment how would you create a drug which will prevent viral attachment.
Antigens are proteins that illicit an immune response from the human body. Some vaccines contain these proteins so the body can provide immunity from the pathogen, such as bacteria that harbor these harmful antigens. What might be some roles for bacteria that would benefit humans in terms of antigen production?
Let’s say there are two closely related viruses, let’s call them Guernsey virus and Micro virus. These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following: A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other. B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same. C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement. D) Not enough information has been given.
True or false: RNA is conserved mechanism in eukaryotes. SDS is an uncharged detergent molecule. Transfection refers to the process of inserting nucleic acid into living prokaryotic cells. when choosing a secondary antibody you do not need to worry about the species in which the primary antibody was generated.
Some microbes cover their antigen markers (protein configuration) with a carbohydrate based material that does not have antigen properties. This covering is called the ___. envelope capsule genome capsid
Which of the following is an example of a pathogen-associated molecular pattern that might be sensed by a Toll-like receptor? Lipopolysaccarides from Gram-negative bacterial outer membranes All of the options listed are correct The spike proteins on the Influenza A virus A unique glycoprotein on the flagella of Trypanosoma cruzi
