Sapurimycin
Sapurimycin is an antitumor antibiotic isolated from Streptomyces DO-116 and belongs to the capramycin family. Sapurimycin exhibits potent activity against Gram-positive bacteria and exhibits significant antitumor effects against leukemia P388 and sarcoma 180 in mouse models. In vitro studies have shown that Sapurimycin can induce single-strand breaks in supercoiled plasmid DNA.

Gram Staining of Tissue Sections
Gram staining of tissue sections is a histochemical technique used to differentiate Gram-positive and Gram-negative bacteria within histological specimens based on differences in bacterial cell wall structure and dye retention, adapted from classical bacteriological Gram staining into tissue-compatible “histological Gram stain” variants. In tissue applications, modifications of the Brown-Hopps and Brown-Brenn methods are commonly used to improve differentiation of microorganisms embedded within host connective tissue and to reduce overstaining or loss of Gram-negative signal, which are known limitations of earlier approaches. The principle relies on crystal violet-iodine complex retention in Gram-positive organisms and subsequent decolorization and counterstaining steps that allow contrast visualization of Gram-negative organisms against tissue background.

Plasmid construction
Plasmid construction refers to the method of producing recombinant plasmid by connecting the target DNA molecule fragment with the DNA molecule of a specific carrier in Escherichia coli.
