Introduction Activation of B cells requires two signals. Depending on the nature of the antigen, the activation of B cells proceeds by two different routes, one dependent on helper T cells (TH cells) and the other not. In the case of T-cells dependent antigen, the interaction between CD40 on B Read more…
Monoclonal antibodies and their side effects One way the body’s immune system attacks foreign substances is by producing large numbers of antibodies. An antibody is a protein that attaches to a specific protein called an antigen. The antibodies circulate throughout the body until they find and attach to the antigen. Read more…
Abstract The immune system plays a crucial role in maintaining the health and protection of the human body against microbial invasions. However, this same system can lead to exaggerated immune and inflammatory responses resulting in adverse outcomes known as hypersensitivity reactions. There are four traditional classifications for hypersensitivity reactions, and Read more…
Wissenschaftler identifizieren Coronavirus-Stamm in Zypern – „Deltacron“, der Delta und Omicron mischt Wissenschaftler in Zypern haben 25 Fälle eines Stammes des Coronavirus gefunden, von dem sie sagen, dass er Elemente der Delta- und Omicron-Varianten kombiniert und ihn „ Deltacron “ nennt , wobei ein hoher Anteil der Variante bei Patienten gefunden wurde, die wegen Covid-19 ins Krankenhaus eingeliefert Read more…
Einige Experten vermuten, dass sich die Omicron-Variante in einem tierischen Wirt entwickelt haben könnte Wenn COVID-19-Varianten auftreten, ist die akzeptierte Weisheit, dass sich die Konstellation von Mutationen, die sie enthalten, in einer immungeschwächten Person entwickelt hat, die sich mit dem Virus infiziert hat und die Infektion nicht abschütteln konnte . Einige Wissenschaftler haben Read more…
Product Description The BrdU Cell Proliferation Assay Package detects 5-bromo-2’-deoxyuridine (BrdU) integrated into mobile DNA throughout cell proliferation utilizing an anti-BrdU antibody. When cells are cultured with labeling medium that incorporates BrdU, this pyrimidine analog is integrated instead of thymidine into the newly synthesized DNA of proliferating cells. After Read more…

Hemocyanins are proteins that use copper binding websites to bind and transport oxygen in a wide range of arthropods and mollusks. Hemocyanin is remoted from the hemolymph of the animals. Hemocyanin is likely one of the strongest antigens recognized. Hemocyanin might be use as an immunological reagent for a few Read more…
Principle COVID-19 Antigen Detection Test is an immunoassay take a look at for fast and qualitative detection of SARS-CoV-2 an infection from swab specimens. Monoclonal anti-SARS-CoV-2 antibodies are coated on the take a look at line area. Antigens of SARS-CoV-2, if current within the specimens will work together with monoclonal Read more…
