Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Details

Target Function	Plays a role in the dissolution of the outermost membrane of extracellular enveloped virions (EV) to allow virion entry into host cells. Participates also in wrapping mature virions (MV) to form enveloped virions (EV).
Subcellular Location	Virion membrane; Single-pass type I membrane protein. Host Golgi apparatus, host trans-Golgi network. Note=B5 is found on enveloped virion (EV) membranes.
Protein Families	Receptors of complement activation (RCA) family
Database References	KEGG: vg:3707658

Gene Functions References

Tanslation of vaccinia virus A27L and B5R genes is independent of PKR activation, but their expression is dependent on the RNase L activity. PMID: 26656695
These results suggest that in the absence of A33, the cytoplasmic tail of B5 contributes to its incorporation into the envelope of progeny virions. PMID: 20378144

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.
