A New Method for the Extraction of R Lipopolysaccharides
Abstract
A method is described which is specific for the extraction of lipopolysaccharides from R form bacteria. The extraction mixture which is monophasic, consists of aqueous phenol, chloroform and petroleum ether. R form lipopolysaccharides (glycolipids). due to their lipophilic nature, are completely soluble in the mixture. S and T form lipopolysaccharides as well as proteins, nucleic acids, and polysaccharides, are insoluble, and they are excluded from the extracts. The method is mild, as it can be carried out at below 10°. The yields are generally higher than those obtained by phenol‐water extraction, and the products are usually water‐soluble. Lipopolysaccharides have been successfully extracted from all R form bacteria so far attempted.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
