| Protein Name / Synonyms | Retinol Binding Protein 4, Plasma Retinol-Binding Protein, PRBP, RBP4 |
| Expressed Region | Glu19-Leu201 |
| Expression System | HEK293 cells |
| Conjugation | Biotin |
| Tag | C-terminal his-tag. The primary amino groups (-NH2) at the N-terminus and the side chains of lysine (K) residues were biotin-conjugated using the standard chemical labeling method. |
| Purity | >95% |
| Purity Determined By | SDS-PAGE under reducing conditions and visualized by Coomassie blue staining |
| Molecular Weight (kDa) | Recombinant protein product has a calculated molecular mass of 20 kDa. Due to the potential post-translational modifications, it migrates as approximately 25 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. |
| Format | Lyophilized powder |
| Formulation | Lyophilized from a 0.2 µm filtered solution in PBS (pH 7.4) |
| Concentration (lot specific) | Determined by BCA protein assay |
| Reconstitution | Briefly spin the vial and bring the contents to the bottom prior to opening. It is recommended to reconstitute at 0.5 - 1.0 mg/mL with sterile deionized water. |
| Research Area | Cardiovascular Disease |
| Shipping Type | Ambient temperature |
| Storage | -20°C |

Storage/Stability
Upon arrival, the lyophilized protein may be stored for 2 weeks at 4°C. For long term storage, it is recommended to store desiccated below -20°C in a manual defrost freezer. Following reconstitution, the protein may be stored for 2 weeks under sterile conditions at -20°C. For long term storage, it is recommended to make appropriate aliquots and store at -80°C. Avoid repeated freeze-thaw cycles.
