Description

The SPG21 protein acts as a negative regulator in CD4-dependent T cell activation, suggesting a potential role in the regulation of immune responses. By interacting directly with CD4, it affects key components of the T cell activation pathway. SPG21 Protein, Mouse (sf9, His) is the recombinant mouse-derived SPG21 protein, expressed by Sf9 insect cells , with N-His labeled tag.

Background

The SPG21 protein appears to function as a negative regulatory factor in CD4-dependent T-cell activation, suggesting a potential role in modulating immune responses. This regulatory function involves direct interactions with CD4, emphasizing its influence on key components of the T-cell activation pathway. Additionally, SPG21 protein interacts with ALDH16A1, indicating its involvement in diverse molecular interactions that may extend beyond T-cell regulation. Further exploration into the specific mechanisms and downstream effects of SPG21 in the context of CD4-dependent T-cell activation could provide valuable insights into its role in immune modulation and cellular processes beyond the immune system.

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
