一般說明

Lennox LB is a highly-referenced microbial growth medium used for the cultivation of E. coli. This nutrient-rich microbial broth contains peptides, amino acids and carbohydrates in a low-salt formulation.

應用

LB Broth with agar (Lennox) has been used for:

  • the transformation of competent E. coli cells
  • to cultivate Ecc-15 bacteria
  • embedding scaffold containing tissue derived from induced pluripotent stem cells (iPSCs)
  • transmission electron microscopy (TEM) and immunohistochemistry (IHC)
It is suitable for non-selective cultivation of E. coli strains for cloning, DNA plasmid production and production of recombinant proteins. Also suitable for selective cultivation when appropriate antibiotics are added, including those that require low-salt conditions, such as Zeocin®.

特點和優勢

Lennox LB powder with agar provides:
  • A budget-friendly alternative to pre-poured plates
  • Easy scale-up using larger package sizes
  • Standard formulation

準備報告

1. Suspend 35 g in 1 L of distilled water.
2. Heat to boiling while stirring to dissolve all ingredients completely.
3. Autoclave for 15 minutes at 121°C.
To prepare Lennox L Agar: Add 1 g glucose and proceed with preparation instructions as above.To prepare the medium of Enquist and Sternberg: Aseptically add 10 ml sterile 1 M magnesium sulfate after autoclaving.

Two-dimensional (2D) nanomaterials have attracted considerable attention in biomedical and environmental applications due to their antimicrobial activity. In the interest of investigating the primary antimicrobial mode-of-action of 2D nanomaterials, we studied the antimicrobial properties of MnO2 and MoS2, toward Gram-positive

LINE-1 (L1) retrotransposons are a notable endogenous source of mutagenesis in mammals. Notably, cancer cells can support unusual L1 retrotransposition and L1-associated sequence rearrangement mechanisms following DNA damage. Recent reports suggest that L1 is mobile in epithelial tumours and neural

Simplicity, efficiency and versatility of the CRISPR/Cas system greatly contributed to its rapid use in a broad range of fields. Applications of unbiased CRISPR/Cas screenings are increasing and thus there is a growing need for unbiased and tailored CRISPR/Cas gRNA

Surgical intervention-related trauma contributes largely to the development of postoperative immunosuppression, with reduced resistance to secondary bacterial infection. This study compared the impact of laparotomy versus laparoscopy on macrophage-associated bactericidal ability and examined whether laparotomy renders the host more susceptible
