Sirius Red F 3B (Direct Red 80) is an azo dye primarily used in staining methods for collagen and amyloid. [1] It has the molecular formula C 45 H 26 N 10 Na 6 O 21 S 6.. In histology, sirius red staining is used in various domains of diagnostic to observe fibrosis levels in a lot of cases of inflammation induced by cancer, vascular or metabolic pathologies.
Braun had been making videos, mainly tutorials, for fun since his teenage years, creating a YouTube channel on March 10, 2014. His first video was uploaded on March 24, 2014, and many of his early videos were recordings of his projects as a laboratory technician or at his parents' garage, with them later being filmed at his industrial-grade laboratory.

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.
Erythrosine, also known as E127 and Red No. 3, is an organoiodine compound, specifically a derivative of fluorone. It is a red-pink dye used for food coloring, cosmetics, hair coloring, pet products, and diverse industrial colorings. [2] [3] It is the disodium salt of 2,4,5,7-tetraiodofluorescein. [2]
Due to a color change from blue to red at pH 3.0–5.2, Congo red can be used as a pH indicator. Since this color change is an approximate inverse of that of litmus, it can be used with litmus paper in a simple parlor trick: add a drop or two of Congo red to both an acid solution and a base solution. Dipping red litmus paper in the red solution ...

mCherry is a member of the mFruits family of monomeric red fluorescent proteins (mRFPs). As an RFP, mCherry was derived from DsRed of Discosoma sea anemones, unlike green fluorescent proteins (GFPs) which are often derived from Aequorea victoria jellyfish. [1]
Red fluorescent protein (RFP) is a protein which acts as a fluorophore, fluorescing red-orange when excited. The original variant occurs naturally in the coral genus Discosoma, and is named DsRed. Several new variants have been developed using directed mutagenesis [1] which fluoresce orange, red, and far-red. [2]
