Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros ' red ' and kytos ' hollow vessel ', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues ...
4.7 to 6.1 million (male), 4.2 to 5.4 million (female) erythrocytes: [13] Red blood cells contain the blood's hemoglobin and distribute oxygen. Mature red blood cells lack a nucleus and organelles in mammals. The red blood cells (together with endothelial vessel cells and other cells) are also marked by glycoproteins that define the different ...
Overall, there are four main types of akaryocytes discovered: Erythrocytes, commonly known as red blood cells, are concave-shaped cells responsible for gas exchange, and the transfer of nutrients throughout an organism. Red blood cells are classified as akaryocytes because they lack a cell nucleus after they have fully developed.
Red blood cells or erythrocytes primarily carry oxygen and collect carbon dioxide through the use of hemoglobin. [2] Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled.

Separating serum proteins by electrophoresis is a valuable diagnostic tool, as well as a way to monitor clinical progress.Current research regarding blood plasma proteins is centered on performing proteomics analyses of serum/plasma in the search for biomarkers.
This can be done in terms of the chemical elements present, or by molecular structure e.g., water, protein, fats (or lipids), hydroxyapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA. In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc.
It does not identify the Rh(D) antigen (Rh blood type). The bedside card method of blood grouping relies on visual agglutination to determine an individual's blood group. The card contains dried blood group antibody reagents fixed onto its surface. A drop of the individual's blood is placed on each blood group area on the card.
Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in cyanobacteria, [1] red algae [2] and cryptophytes, [3] accessory to the main chlorophyll pigments responsible for photosynthesis.The red pigment is due to the prosthetic group, phycoerythrobilin, which gives phycoerythrin its red color.
