Giemsa stain, modified
|
Giemsa stain, modified has been used in: • The Boyden chamber assay to study leukocyte chemotaxis. • Determining the number of chromosomes present in cells of newly synthesized skin tissue. • Chromosome aberration test.
When blood films are stained using Giemsa Stain, the nucleus and cytoplasm of white blood cells take on characteristic blue or pink coloration. The use of purified eosin and thiazine dyes minimizes lot-to-lot variation.

Poly-L-lysine solution 0.1 % (w/v) in H2O
|
Poly-L-lysine polymers can be used in promoting cell adhesion to solid substrates, conjugation to methotrexate for increased drug transport, microencapsulation of islets, cell microencapsulation technology, microarray glass slide coating, and chromosomal preparations. Lower molecular weight poly-L-lysine (30,000-70,000) is less viscuous in solution, but higher molecular weight versions provide more attachment sites per molecule. Poly-L-lysine solution has been used for the attachment of endothelial cell cross sections to UV-crosslinked PET membrane frame slides. Poly-L-lysine coated slides were used for the placement of tissue sections for immunohistochemical assay.
