In 1966, a decade after RSV was discovered, US National Institutes of Health researchers began testing an RSV vaccine made of a virus killed with formalin—an aqueous solution of formaldehyde. The trial was a disaster, McLellan says. Although infants who got the vaccine developed antibodies against the virus, they were not protected from infection.

—Technique eases analysis of damaged RNA “New method allows researchers to analyze gene expression in preserved tissue biopsy samples” When doctors take biopsies of a patient’s tissue, they often fix the tissue with formalin and embed it in wax to preserve it. But this process chemically modifies and fragments mRNAs in the tissue, making it difficult to analyze the mRNAs later to, for example, study gene expression patterns.

The researchers separated cells from human and rodent brain tissue samples—fixed using preservatives such as formalin, zinc, and paraformaldehyde—by passing liquefied frozen tissue through needles multiple times and applying an enzyme solution that cleaves chemical bonds between cells. They then fluorescently tagged the cells and passed cell suspensions through a flow cytometer to isolate two types of neurons.

Leaks, spills, and other exposures: Five gallons of formalin spilled at courier surface Dunham Express in Wisconsin Nitric acid spilled at Advanced Precision Anodizing in Oregon I believe this is at Scripps Research Institute's La Jolla, Calif., site: "A lab worker was mixing together hot and cold substances" when a test tube broke, and he was injured on his face Not covered (usually): meth labs; ammonia leaks; incidents involving floor sealants, cleaning solutions, or pool chemicals; transportation spills; things that happen at recycling centers (dispose of your waste properly, people!)

gas caught fire and exploded; three worders were injured A fire at India's Physical Research Laboratory started in an waste storage area Leaks, spills, and other exposures: Boron trifluoride leaked from a cylinder being shipped from Idaho National Laboratory to a nuclear reactor Formalin spilled when a worker dropped a container at a medical center in Massachusetts, a Canadian hospital had a formaldehyde spill, and hydrochloric acid spilled at a dental lab in North Dakota Two students passed out in a lab involving ethanol and food coloring at Baylor University Radioactivity detected in a University of Memphis scrap metal dumpster turned out to be from an old "metal door apparatus" that contained naturally radioactive materials Not covered: meth labs; ammonia leaks; incidents involving floor sealants, cleaning solutions, or pool chemicals; transportation spills; and fires from oil, natural gas, or other fuels. http://cenblog.org/the-safety-zone/2012/04/friday-chemical-safety-round-up-38 2012-04-20 17:43:09.0 http://cenblog.org/the-safety-zone/ /the-safety-zone/ Friday chemical safety round-up Jyllian Kemsley

Formaldehyde was likely used as a dilute solution known as formalin, says Anna N. Dhody, curator of the Mütter Museum, in Philadelphia. “It cross-links the amino acids in tissues and inhibits the natural decomposition process,” she says. Bleach and detergent get rid of odors or bacteria but aren’t preservatives, she adds.

A cross-linking reagent, such as a solution of formaldehyde gas in water that can go by the name of formalin or methylene glycol, accomplishes the fusion. “Formaldehyde is a very small molecule—it diffuses into hair extremely quickly,” says Yashavanth Kamath, a hair fiber expert and former director of the Textile Research Institute in Princeton, N.J.
