BIOTECHNOLOGY

Aprotinin

Aprotinin is a monomeric (single-chain) globular polypeptide derived from bovine lung tissue. It consists of 16 different amino-acid types

Small amounts of aprotinin can be added to tubes of drawn blood to enable laboratory measurement of certain rapidly degraded proteins such as glucacon

In cell biology aprotinin is used as an enzyme inhibitor to prevent protein degradation during lysis or homogenization of cells and tissues.

BSA

Bovine serum albumin (BSA) is a serum albumin protein derived from cows. It is often used as a protein concentration standard in lab experiments. BSA has numerous biochemical applications including ELIZAs (Enzyme-Linked Immunosorbent Assay), immunoblots, and immunohistochemistry. Because BSA is a small, stable, moderately non-reactive protein, it is often used as a blocker in immunohistochemistry.

ANIMAL BLOOD PLASMA

Blood plasma is the liquid component of blood. Blood cells are in suspension inside. It makes up 55% of the total volume of blood.
It is used to transport blood cells and hormones through the body. The extraction of blood plasma is performed by centrifugation. The yellowish fluid observed after this operation is blood plasma. The plasmas we offer are produced at our Elerbeck site in the Hamburg region.

ANIMAL BLOOD SERUM

The blood serum consists mainly of water, of a yellowish colour. It dissolves with proteins, hormones, minerals and carbon dioxide. It is therefore a very important source of electrolytes. It contains neither platelets, nor white and red blood cells, nor fibrinogens. It is used for grafts (rejection limitation) or for some diagnostics difficult to do with plasma. We offer different qualities as well as different origins and species. The serums we manufacture are produced at our Elerbeck site in the Hamburg region.

STREPTOKINASE

Streptokinase is an enzyme made up of proteins that accelerate the reactions inside the body without modifying themselves, and without modifying the components involved in this reaction.
This enzyme is produced by streptococci (a variety of bacteria) that are able to digest fibrin and dissolve blood clots.
