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.

Database References
Tissue Specificity Highly expressed in PYS-2 parietal endoderm cells and in the kidney. The RNA level increased about 10-fold during differentiation of F9 embryonal carcinoma cells to parietal endoderm cells.

Gene Functions References

  1. RAP deficiency attenuated atherosclerosis without influencing abdominal aortic aneurysms in hypercholesterolemic mice infused with angiotensin II. PMID: 22153700
  2. Findings reveal that RAP is a novel Abeta-binding protein that promotes cellular internalization of Abeta. PMID: 19826010
  3. In RAP-deficient mice megalin expression was strongly reduced and restricted to a subapical localization and NaP(i)-IIa protein distribution and abundance in the kidney was not altered. PMID: 12748857
  4. the His-sRAP-induced acceleration of megalin-mediated endocytosis causes phosphaturia via altered subcellular distribution of NaPi-II [39-kD receptor-associated protein (RAP)] PMID: 15976002
  5. Results suggest that receptor-associated protein is required for the establishment of thyroglobulin reservoirs, but its absence does not affect hormone secretion. PMID: 16306127
  6. RAP is expressed by thyrocytes in a TSH-dependent manner, both in cultured thyroid cells and in vivo PMID: 17123336
  7. Disruption of the RAP gene determines not only thyroid abnormalities, but also a severe defect of megalin expression and function in the kidney. PMID: 18296906
  8. Receptor-associated protein (RAP) plays a central role in modulating Abeta deposition in APP/PS1 transgenic mice PMID: 18776935

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
