||Recombinant Human Inhibin beta A chain/Activin A/INHBAB is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Gly311-Ser426) of Human Activin A.
||Inhibin beta A chain,INHBA,Activin A
||Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4
||The product is shipped at ambient temperature.
||Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS or distill water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
||Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.
||Measured by its ability to binding Activin IIB used funtional ELISA.
||Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.
||Less than 0.1 ng/µg (1 IEU/µg).
|Amino Acid Sequence
||Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Activins, members of the TGF-beta superfamily, are disulfide-linked dimeric proteins originally purified from gonadal fluids as proteins that stimulated pituitary follicle stimulating hormone (FSH) release. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Activins are homodimers or heterodimers of the various beta subunit isoforms, while inhibins are heterodimers of a unique alpha subunit and one of the various beta subunits.
