Description

The staining method according to Leishman is one of the standard techniques in hematological diagnostic procedures. Like Wright’s eosin methylene blue solution and May-Grünwald’s eosin methylene blue solution, it is used for staining of blood and bone marrow smears and clinical cytological specimens. The typical resulting color of cell nuclei is red to purple, which depends on the buffer tablets (Buffer tablets pH 7.2 or Buffer tablets pH 6.8). 500 mL of the IVD & CE-registered Leishman’s eosin methylene blue solution are sufficient for staining up to 1600 slides in Hellendahl cells. It is registered as IVD and CE product.

Application

For microscopy. For staining of blood and bone marrow smears and clinical-cytological specimens

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved.

Description

LB-Broth is based on the formulation of MILLER (1972) supporting the growth of E. coli. Casein peptone and yeast extract supply essential growth factors, such as nitrogen, carbon, sulfur, minerals and vitamins.

Typical Composition of LB-Broth (Miller, Merck)

Preparation of LB Broth (Miller)

Suspend 25 g LB-Broth in 1 litre of demineralized water and autoclave for 15 min at 121 °C.  at 25 °C (pH: 7.0 ± 0.2). The prepared broth is clear and yellowish-brown.

Experimental Procedure

According to appropriate use or purpose. Incubation: 24 h at 35-37 °C aerobically.
