Note: The complete sequence including tag
sequence, target protein sequence and linker sequence could be provided upon request.
Protein Length
Full Length of Mature Protein
Tag Info
N-terminal 6xHis-tagged
Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer,
6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
The first step of making this recombinant Human SEMA7A protein is synthesizing the SEMA7A gene, the synthesized gene is then cloned into an expression vector which is a cDNA plasmid that includes a promoter sequence and an antibiotic-resistant gene. It also has N-terminal 6xHis tag encoding a fusion tag for downstream protein purification or identification. The antibiotic-resistant gene enables the selection of cells carrying the plasmid in antibiotic-based media and then transfects cells with a DNA vector that contains the template and then culturing the cells so that they transcribe and translate the desired protein. The recombinant SEMA7A protein is purified by ion-exchange chromatography or affinity purification. And the purity is 90%+ by SDS-PAGE.
SEMA7A plays a role in both innate and adaptive immune systems. It is a strong stimulator of monocytes in innate immunity, inducing the generation of pro-inflammatory cytokines. While SEMA7A works as a regulator of the T-cell immune response in adaptive immunity due to its effects on T-cell proliferation. SEMA7A can regulate T cell responses via the α1β1 integrin receptor. SEMA7A is a glycosylphosphatidylinositol (GPI)-anchored membrane protein with chemoattractant and chemorepulsive attributes. In addition to its role in guiding axon pathfinding during neuronal development, SEMA7A has diverse functions in morphogenesis and immune cell control.
