CD99 Protein, Mouse (HEK293, Fc)

Cat. No.: HY-P75366
COA Handling Instructions

CD99 Protein facilitates T-cell adhesion and aids leukocytes in crossing the endothelial basement membrane during leukocyte extravasation. It functions alongside PECAM1 but acts independently. CD99 Protein forms a homodimer and interacts with PILRB. CD99 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived CD99 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CD99 Protein, Mouse (HEK293, Fc) is 110 a.a., with molecular weight of 47-55 kDa.

Description

CD99 Protein facilitates T-cell adhesion and aids leukocytes in crossing the endothelial basement membrane during leukocyte extravasation. It functions alongside PECAM1 but acts independently. CD99 Protein forms a homodimer and interacts with PILRB. CD99 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived CD99 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CD99 Protein, Mouse (HEK293, Fc) is 110 a.a., with molecular weight of 47-55 kDa.

Background

CD99 Protein is involved in T-cell adhesion processes and plays a crucial role in a late step of leukocyte extravasation, assisting leukocytes in overcoming the endothelial basement membrane. It operates at the same site as PECAM1, but functions independently. CD99 Protein forms a homodimer and interacts with PILRB.

Biological Activity

Immobilized Mouse CD99 Protein at 5 µg/mL (100 µL/well) can bind Mouse PILR-alpha protein. The ED50 for this effect is 0.2712 μg/mL, corresponding to a specific activity is 3687.316 Unit/mg.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

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)
× = ×
C1   V1   C2   V2

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
