Description

Semaphorin-7A/SEMA7A proteins critically regulate integrin-mediated signaling, affecting cell migration and immune responses. It promotes focal adhesion complex formation, activates PTK2/FAK1, and leads to the phosphorylation of MAPK1 and MAPK3. Semaphorin-7A/SEMA7A Protein, Mouse (HEK293, C-6His) is the recombinant mouse-derived Semaphorin-7A/SEMA7A, expressed by HEK293 , with C-6*His labeled tag. ,

Background

The Semaphorin-7A/SEMA7A protein plays a crucial role in integrin-mediated signaling, contributing to the regulation of cell migration and immune responses. It facilitates the formation of focal adhesion complexes and activates the protein kinase PTK2/FAK1, leading to the subsequent phosphorylation of MAPK1 and MAPK3. Moreover, it enhances the production of pro-inflammatory cytokines by monocytes and macrophages. This protein also plays a significant role in modulating inflammation and T-cell-mediated immune responses. Additionally, it promotes axon growth in the embryonic olfactory bulb and aids in the attachment, spreading, and dendrite outgrowth in melanocytes. It interacts with PLXNC1 and the integrins ITGA1 and ITGB1.

Biological Activity

Measured by the ability of the immobilized protein to support the adhesion of THP‑1 human acute monocytic leukemia cells. When 5×104 cells/well are added to coated plates, cell adhesion is enhanced in a dose dependent manner after 60 minutes at 37 °C. The ED50 for this effect is 0.2644 μg/mL, corresponding to a specific activity is 3.782×103 U/mg.

Molecular Weight

Approximately 75-90 kDa due to the glycosylation.

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
