Recombinant Human/Mouse/Rat Activin A Protein
产品特性
| Synonyms: | Inhibin beta A chain; INHBA; Activin A |
| Product Description: | Recombinant Human Activin A is produced by our Mammalian expression system and the target gene encoding Gly311-Ser426 is expressed. |
| UniProt ID: | P08476 |
| Species: | Human/Mouse/Rat |
| Expression System: | Human Cells |
| Tag: | Tag free |
| Predicted MW: | 13 KDa |
| SDS-PAGE: | 15 KDa, reducing conditions |
| Formulation: | Lyophilized from a 0.2 μm filtered solution of 4mM HCl. |
| Endotoxin Level: | Less than 0.001 ng/µg (0.01 EU/µg) as determined by LAL test. |
| Activity: | Measured by its ability to induce SMAD signaling in 293-Activin A Res cells. The ED50 for this effect is 1.3 ng/ml. |
| Purity: | >95% |
| Reconstitution: | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. |
| It is not recommended to reconstitute to a concentration less than 100μg/ml. | |
| Dissolve the lyophilized protein in distilled water. | |
| Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | |
| Stability and Storage: | 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. |

产品背景
Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. 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. Inhibins appear to oppose the functions of activins.
