Woodworking, paper glue, fireproof laminates Medieval or earlier Soybean glue: As for casein glue, but using soy protein Soy protein is mixed with alkalis Albumin glues (blood glues and egg albumin adhesive, EAA) blood (serum albumin) or eggs: prehistoric Gelatin glues hide glue, including rabbit-skin glue; bone glue, and fish glue including ...
The concept of "molecular glue" originated in the late 20th century, with immunosuppressants like cyclosporine A (CsA) and FK506 identified as pioneering examples. [2] CsA, discovered in 1971 during routine screening for antifungal antibiotics, exhibited immunosuppressive properties by inhibiting the peptidyl–prolyl isomerase activity of cyclophilin, ultimately preventing organ transplant ...
Animal glue in granules. Animal glue is an adhesive that is created by prolonged boiling of animal connective tissue in a process called rendering. [1] In addition to being used as an adhesive, it is used for coating and sizing, in decorative composition ornaments, and as a clarifying agent.
A similarly strong, rapidly adhering glue - which contains 171 different proteins and can adhere to wet, moist and impure surfaces - is produced by the very hard [5] [6] limpet species Patella vulgata; this adhesive material is a very interesting subject of research in the development of surgical adhesives and several other applications.
Hide glue is measured on the basis of its gel strength, a measure of how many grams of force it requires to depress a 1 ⁄ 2 in (13 mm) plunger 4 mm (0.16 in) into a 12.5% protein solution of the glue at 10 °C (50 °F). Glue is manufactured in standard grades from 32–512 grams (1.1–18.1 oz). 192-gram (6.8 oz) strength is the most commonly ...

The mixed type, which occurs if the crack propagates at some spots in a cohesive and in others in an interfacial manner. Mixed fracture surfaces can be characterised by a certain percentage of adhesive and cohesive areas. The alternating crack path type which occurs if the cracks jump from one interface to the other. This type of fracture ...
Influenza strains are named for the specific hemagglutinin variant they produce, along with the specific variant of another surface protein, neuraminidase. These hemagglutinins are subject to rapid evolution via antigenic shift and drift in the influenza avian reservoir. This results in new subtype of hemagglutinins being created frequently ...
