Description

CD40 Protein, a vital TNFR superfamily member, lacks conserved residue(s) crucial for feature annotation propagation, indicating unique structural attributes. This distinctiveness may influence CD40's functional interactions within the TNFR superfamily, underscoring the need for further exploration to unravel its specific roles and regulatory mechanisms in cellular signaling pathways. CD40 Protein, Rhesus Macaque (HEK293, His) is the recombinant Rhesus Macaque-derived CD40 protein, expressed by HEK293 , with C-10*His labeled tag. The total length of CD40 Protein, Rhesus Macaque (HEK293, His) is 173 a.a., with molecular weight of ~31.67 kDa.

Background

CD40, a crucial member of the TNFR superfamily, is characterized by the absence of conserved residue(s) necessary for the propagation of feature annotation. This distinctive feature suggests unique structural attributes in CD40, potentially influencing its functional interactions within the TNFR superfamily. The lack of these conserved residues underscores the specific nature of CD40 and emphasizes the importance of further exploration to unravel its distinct roles and regulatory mechanisms in cellular signaling pathways.

Help & FAQs
  • How should lyophilized recombinant proteins be reconstituted and stored?

    1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss. 2. Taking 10 μg as an example, first add 20 μL of reconstituted solution provided by MCE and use a pipette to gently resuspend the lyophilized protein until it is fully dissolved.. (For most proteins, the reconstitution solution we provide is sterile water. If a diluent other than water is required, it will be indicated in the product's Certificate of Analysis (COA).). 3. Add an additional 80 μL of buffer/culture medium containing carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% trehalose), and then use a pipette to gently mix until uniform. The final concentration is should not be lower than 100 μg/mL. 4. Aliquot at least 20 μL per tube. 5. After aliquoting, store it frozen at a temperature ranging from -20ºC to -80ºC, and it can be preserved for 3 to 6 months.

  • How should solution-form recombinant proteins be stored?

    1. The product can be stored in its original form and diluted as needed upon use. 2. Alternatively, dilute with a buffer/culture medium containing a carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% alginate), mix well by pipetting, and ensure that

  • Why is it necessary to add carrier proteins?

    Carrier proteins are commonly added to enhance the stability of recombinant proteins, preventing them from adhering to the walls of the container during freezing or thawing processes. Plastic tubes have a certain adsorptive capacity for proteins, which may lead to difficulty in separating the protein from the tube walls, resulting in a decrease in the actual concentration of the protein in the solution and thus affecting its activity. To minimize such losses, it is recommended to add a commonly used carrier protein solution prior to the long-term storage of recombinant protein products.

  • Carrier protein types and options?

    In cases where the carrier protein is not expected to influence the experimental outcomes, an appropriate carrier protein, such as 0.1% BSA (Bovine Serum Albumin), 5% HSA (Human Serum Albumin), 10% FBS (Fetal Bovine Serum), or 5% trehalose, can be incorpo
