The smallest molecular weight Ig is?
The smallest molecular weight immunoglobulin is IgG, specifically the IgG4 subclass. This immunoglobulin isotype is the smallest in size among the IgG subclasses, weighing approximately 150 kDa.
What is the name given to a microorganism that can exist only in the absence of oxygen?
An anaerobic microorganism.
How many CCl4 molecules of different masses can exist?
Only one type of CCl4 molecule can exist, as it is a specific chemical compound with a defined molecular structure consisting of one carbon atom and four chlorine atoms. Therefore, there is only one possible mass for a CCl4 molecule.
At room temperature there are only two elements bromine and mercury that exist as what?
Bromine and mercury exist as liquids at room temperature. Bromine is a dark red-brown liquid, while mercury is a silvery liquid.
What are the only element that exist in nature as isolated atoms?
Noble gases, such as helium, neon, and argon, exist in nature as isolated atoms because they have a stable electron configuration. These elements do not readily form chemical bonds with other elements.
What Ig is a pentamer?
IgM
Is IGG a pentamer?
No. It is a monomer.
Why immunoglobulin G alone can cross placenta?
IgG is an immunoglobluin monomer, meaning that it is one immunoglobulin that is small enough to cross the placenta. An example would be the Rh antibody that causes isoimmunization between Rh negative mothers and Rh positive fetuses. In constrast, ABO blood group immunoglobulins are IgM which is a pentamer, meaning it is composed of 5 immunoglobulins and is too large to cross the placenta.
Which antibody classes is usually arranged as a pentamer?
IgM
Immunoglobulin A Qn?
what is immunoglobulin for
What Immunoglobulin is released in an allergic reaction?
Immunoglobulin E (IgE)
What are the classes of antibodies?
There are five immunoglobulin classes (isotypes) of antibody molecules found in serum: IgG, IgM, IgA, IgE, and IgD. IgA (immunoglobulin A) IgD (immunoglobulin D) IgE (immunoglobulin E) IgG (immunoglobulin G) IgM (immunoglobulin M)
What does an elevated immunoglobulin after thyroidectomy indicate?
what does an elevated immunoglobulin after thyroidectomy indiate
What is immunoelectrophoresis?
also called gamma globulin electrophoresis, or immunoglobulin electrophoresis, is a method of determining the blood levels of three major immunoglobulins: immunoglobulin M (IgM), immunoglobulin G (IgG), and immunoglobulin A (IgA).
What immunoglobulin is present in breast milk?
The immunoglobulin present in breast milk is called IgA.
What are other names for antibodies?
1. Surface Immunoglobulin (slg) 2. Membrane Immunoglobulin (mlg)
What is the main immunoglobulin of the respiratory tract?
The main immunoglobulin of the respiratory tract is Immunoglobulin A (IgA). It plays a crucial role in defending against pathogens that enter through the respiratory mucosa by neutralizing and preventing their attachment to the mucosal surface.
