Descrição geral

Formaldehyde (formalin) is produced by oxidation of methanol. It is made of 37% formaldehyde and impurities such as methanol, small amounts of formic acid, aldehydes and ketones. It is used as a denaturant in formaldehyde-agarose gel electrophoresis of RNA. A gel concentration of 2.2M formaldehyde is typically used. The formaldehyde concentration as supplied is approximately 13.3M.

Aplicação

Formaldehyde solution has been used for fixing of cells and tissue sections. It has been used in the formaldehyde agarose gel electrophoresis. Formaldehyde is used as a denaturant in formaldehyde-agarose gel electrophoresis of RNA.

Embalagem

25, 500 mL in poly bottle

Nota de análise

Tested for use in formaldehyde-agarose gel electrophoresis of RNA.

Insight into high-resolution three-dimensional genome organization and its effect on transcription remains largely elusive in plants. Here, using a long-read ChIA-PET approach, we map H3K4me3- and RNA polymerase II (RNAPII)-associated promoter-promoter interactions and H3K9me2-marked heterochromatin interactions at nucleotide/gene resolution in rice.

Asthenozoospermia (AZS), also known as asthenospermia, is characterized by reduced motility of ejaculated spermatozoa and is detected in more than 40% of infertile patients. Because the proportion of progressive spermatozoa in severe AZS is <1%, severe AZS is an urgent
