Abstract:
Six types of hemocytes were identified in fifth instars of the Indian meal moth, Plodia interpunctella. The morphology of these cells was characterized by phase contrast and electron microscopy, with Sudan black B, Giemsa, Janus green B, and periodic acid-Schiff staining. Reaction of the hemocytes with seven fluorescing lectin conjugates revealed distinctive binding patterns by their plasma and nuclear membranes and cytoplasmic inclusions. A direct line of descent from prohemocytes to plasmatocytes to granulocytes is suggested from these morphological observations.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
