α-Naphthyl butyrate esterase, also referred to as naphthyl butyrate esterase or butyrate esterase, is a histological stain specific for white blood cells of the monocytic proliferation line. [ 1 ] References
Acquired C1 esterase inhibitor deficiency, also referred to as acquired angioedema (AAE), is a rare medical condition that presents as body swelling that can be life-threatening and manifests due to another underlying medical condition.
Carboxylesterase 1 is a serine esterase and member of a large multigene carboxylesterase family. It is also part of the alpha/beta fold hydrolase family. [ 7 ] These enzymes are responsible for the hydrolysis of ester- and amide -bond-containing xenobiotics and drugs such as cocaine and heroin.
The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ratio was an estimate made in 1972; current estimates put the ratio at either 3 to 1 or 1.3 to 1. [301] The total length of capillaries in the human body is not 100,000 km.

The enzyme protein phosphatase methylesterase-1 (EC 3.1.1.89, PME-1, PPME1; systematic name (phosphatase 2A protein)-leucine ester acylhydrolase [1] [2] catalyses the reaction [phosphatase 2A protein]-leucine methyl ester + H 2 O ⇌ {\displaystyle \rightleftharpoons } [phosphatase 2A protein]-leucine + methanol
Cytochemical properties of the leukemic cells must be typical of mast cell derivation (presence of metachromatic granules staining with alpha-naphthyl chloroacetate esterase, but not with peroxidase). [6] Mast cell tryptase is an enzyme contained in mast cell granules. Mast cell numbers are best estimated by tryptase immunostaining because very ...
