| Short Description: |
This ESR2 Sandwich ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human cell culture supernatant, serum and plasma (EDTA, citrate, heparin). |
| Storage Instruction: |
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual. |
| Assay Time: |
3.5h |
| Detection: |
Colormetric |
| Gene Symbol: |
ESR2 |
| Gene ID: |
2100 |
| Uniprot ID: |
ESR2_HUMAN |
| Specificity: |
This kit recognizes Human ER Beta in samples. No significant cross-reactivity or interference between Human ER Beta and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Post Translational Modifications | Phosphorylation at Ser-87 and Ser-105 recruits NCOA1. |
| Function | Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1/ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform 2: Lacks ligand binding ability and has no or only very low ERE binding activity resulting in the loss of ligand-dependent transactivation ability. |
