IgG1 is the most abundant immunoglobulin in the blood. It is able to cross the placenta and activate the complement system.

IgG2 is present in lower levels than IgG1 and doesn't cross the placenta. It activates complement but has lower affinity for phagocytes.

IgG3 has a shorter half-life than IgG1 and IgG2, but it is an effective activator of complement.

IgG4 does not activate complement and has a moderate affinity for phagocytes.

These serum concentrations indicate the relative abundance of each IgG type in the blood.

The process of repeatedly clenching and unclenching the fist during venipuncture.

Increased levels of potassium, lactic acid, calcium, and phosphorus in the blood, and a lower pH.

A type of microscope that uses specialized optics to enhance the contrast of transparent specimens, allowing for clearer visualization of details.

A powerful microscope that uses a beam of electrons instead of light to create high-resolution images of small objects.

A standard microscope that illuminates the specimen from below using a light source and lenses to magnify the image.
