Indicators
A tetrameric complex of 2 molecules of hemoglobin subunit alpha (encoded by either the HBA1 or HBA2 gene) and 2 molecules of a hemoglobin subunit beta variant where the glutamic acid residue at position 7 has been replaced by valine.
Tests
The determination of the amount of HLA DP Alpha 1 antigen present in a sample.
Indicators
A physiological progestin that is produced during glucocorticoid and steroid hormone synthesis and is increased during the third trimester of pregnancy. Hydroxyprogesterone binds to the cytoplasmic progesterone receptors in the reproductive system and subsequently activates progesterone receptor mediated gene expression.
Indicators
Gonadal glycoprotein hormone, Inhibin A, consists of an alpha subunit covalently linked to a beta-A subunit and strongly inhibits pituitary FSH secretion. Serum concentrations transit during the menstrual cycle. Dimers of the beta subunit (a TGF-beta superfamily member), termed activin, are potent stimulators of FSH secretion. (from OMIM 147380 and NCI)
Indicators
Inhibin B, consisting of an alpha subunit and a beta B subunit linked by disulphide bonds, is a heterodimer hormone produced by the follicle cells of the ovary and by the Sertoli and Ledig cells of testis. Although other forms of inhibin also exist in men, inhibin B is the predominant form in the circulation in men.
Indicators
A class of interferon (leukocyte interferon) produced predominantly by B lymphocytes. Located in a cluster on 9p22 there are at least 13 functional genes and 1 pseudogene.
Tests
The determination of the amount of interferon alpha present in a sample.
Tests
The determination of the amount of interleukin-1 alpha present in a sample.
Indicators
A heterodimeric cytokine composed of interleukin-12 subunit beta and interleukin-23 subunit alpha. This complex binds to the interleukin-23 receptor complex, which activates the JAK-STAT signaling pathway and modulates the proliferation, differentiation and effector functions of T-lymphocytes, natural killer cells and some myeloid lineage cells.
Tests
The determination of the amount of interleukin-4 receptor subunit alpha in a sample.
Tests
The determination of the amount of leucine rich alpha-2-glycoprotein 1 present in a sample.
Tests
The determination of the amount of lymphotoxin alpha in a biological sample.
