Fab fragments from polyclonal anti-fluorescein antibodies, conjugated to alkaline phosphatase.
After immunization with fluorescein, the sheep IgG was purified by ion exchange chromatography and the specific IgG was isolated by immunosorption. The Fab fragments obtained by papain digestion were purified by gel filtration, conjugated with alkaline phosphatase, and stabilized in 50 mM triethanolamine buffer, 3 M NaCl, 1 mM MgCl2, 0.1 mM ZnCl2, 1% bovine serum albumin (w/v), pH 7.6.
Clone: polyclonal
Ig class: sheep IgG, Fab fragments
Anagrelide belongs to the imidazo[2,1-b]quinazolin-2-one series of compounds.

Biochem/physiol Actions

Anagrelide is a phosphodiesterase inhibitor with antiplatelet activity (IC50 = 36 nM for inhibition of phosphodiesterase-III). Anagrelide inhibits the maturation of megakaryocytes into platelets, reducing both megakaryocyte hyperproliferation and differentiation. As a drug, anagrelide is antithrombocythemic used for the treatment of overproduction of blood platelets.
Anagrelide is a phosphodiesterase inhibitor with antiplatelet activity.
In human and animals, anagrelide has an inhibitory effect on platelet aggregation. Small doses of anagrelide can generate thrombocytopenia. Anagrelide is not advised during pregnancy. It is effectively used in the treatment of essential thrombocytosis.

Neutrophils are important innate immune cells that tackle invading pathogens with different effector mechanisms. They acquire this antimicrobial potential during their maturation in the bone marrow, where they differentiate from hematopoietic stem cells in a process called granulopoiesis. Mature neutrophils

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
