Form | Liquid or Lyophilized powder |
Buffer | Liquid form: default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Lyophilized powder form: the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. |
Reconstitution | Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%. |
Storage | 1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C. |
Notes | Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. |

- CRABP I plays an important role not only in mediating the retinoid effects, but also in modulating the radiation sensitivity of tumour cells after combined retinoic acid radiation treatment. PMID: 14713576
- increased CYP26-mediated catabolism of retinoic by CRABP-I transfection might decrease the amount of retinoic acid that is accessible to the nuclear receptors PMID: 15281009
