What is Acridine Orange
Product name: Acridine Orange
CAS: 10127-02-3
Molecular Formula: C34H40Cl4N6Zn
Molecular Weight: 739.9426
Product Description: orange powder. Soluble in water, ethanol. The solution for the orange fluorescent green belt. PH value of 8.4-10.4, no fluorescence. Can be between two adjacent pairs of bases, the part liberated from the double helix of DNA, the two bases of expansion of the spacer. Such a DNA replication process can increase the DNA strand or a missing base, which causes mutations in the reading frame. As a fluorescent tracer, tumor cells and bacteria, nucleic acid staining and mutagenic mutations of the reading frame. The acridine orange is a kind of fluorescent pigment, acridine orange filter wavelength of 488 nm. Filter wavelength blocking at 515 nm. Acridine orange combined with DNA and RNA in the volume of the cell, there is a difference, but a different color fluorescent specificity (grayed), this is because DNA is a high-absorption polymer The location of fluorescent material is lower, green fluorescence hair low degree of polymerization and RNA material can and fluorescent associated with the location of the greatest number, so that the red fluorescence of the hair.

Haematoxylin price
Product Name: Haematoxylin
CAS: 517-28-2
Molecular Formula: C16H14O6
Molecular Weight: 302.28
Product Description: One of the most commonly used dyes and dyes is a kind of natural media. Used for silk, fur and leather dyeing and cotton printing, available in blue or black color spots. In aqueous solution, in particular in a simple oxidation of the alkaline solution by air oxidation with red-brown hematoxylin. Hematoxylin can not dye should be exposed to the Belüftungsort make oxidation-hematoxylin (also called wood grain) to use, which is "mature". Hematoxylin process "mature" takes longer, more configuration, the strength of coloring is stronger. Dyed material must be made by metallic salts as an agent before dyeing the force. Thus, in the manufacture of hematoxylin dye with mordants.

Propidium iodide
Product Name: Propidium iodide
CAS: 25535-16-4
Molecular Formula: C27H35N4
Molecular Weight: 415.5931
Product Description: staining of the nucleus of reagents for DNA, which is commonly used in the detection of cellular apoptosis, the full English name is propidium iodide. It is a kind of ethyl bromide body analogs that release red fluorescence after coating the double-stranded DNA. Although PI can not live through the cell membrane, but can by damaging the cell membrane and nuclear staining. PI is often used with calcein - AM or fluorescent probes are used together, such as FDA for dyeing on living cells and dead cells at the same time.
