Recombinant Human Activin A (INHBA)
Product Details
| Gene ID | 3624 |
| Accession | P08476 |
| Alternative Name | Activin beta-A chain, Inhibin beta-A chain, Erythroid differentiation protein, INHBA, FSH releasing protein |
| Species | Human |
| Source | E. coli |
| Description | Part of the TGF-? family, inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic, pituitary and gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development and bone growth depending on their subunit composition. Activin A is a disulfide linked homodimer (two beta-A chains) that binds to the two forms of activin receptor type I (Act RI-A and Act RI-B) and two forms of activin receptor type II (Act RII-A and Act RII-B). The biological activities of Activin A can be neutralized by inhibins and by the diffusible TGF-? antagonist, follistatin. Recombinant Human Activin A is a homodimeric, non-glycosylated protein that has a molecular weight of 26 kDa. |
| Accession | P08476 |
| Functions | The ED(50) as determined by the ability to induce cytotoxicity of MPC-11 cells was found to be 1-1.5 ng/ml |
| Formulation | Lyophilized from a concentrated protein solution containing 0.02% TFA |
| Solubility | A quick spin of the vial followed by reconstitution in sterile distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Appearance | Lyophilized Powder |
| Molecular Weight | 13 |
| Purity | >95% as determined by SDS-PAGE |
| Concentration | <1.0 EU/μg of recombinant protein as determined by the LAL method |
| Shipping Condition | Ambient Temperature |
| Storage Condition | The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine can be stored in working aliquots at 2? – 8?C for one month, or at -20?C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. |
