产品简介:
Product Summary:
The Gram stain was devised in 1884 by Christian Gram in an attempt to differentiate bacterial cells from infected tissue. Although Gram observed what is now called the ?Gram reaction,? he did not recognize the taxonomic value of his technique.
The Gram stain is now used to differentiate intact, morphologically similar bacteria into two groups based on cell color after staining. In addition, cell form, size and structural details are evident. Such preliminary information provides important clues to the type of organism(s) present and the further techniques required to characterize them.
Because inorganic iodine is rapidly oxidized and loses its effectiveness as a mordant,1 the Gram Stain Kit (Cat. No. 212539) differs from Gram?s original formulation by offering a more stable organic iodine complex, L-polyvinylpyrrolidone-iodine. |
