CD63 Protein, Human/Cynomolgus (HEK293, His)

Cat. No.: HY-P76243
SDS COA Handling Instructions

The CD63 protein serves as a cell surface receptor for TIMP1 and is critical for activating signaling cascades. It contributes to ITGB1 and integrin signaling, activating AKT, FAK/PTK2 and MAP kinases to promote cell survival, cytoskeletal reorganization, adhesion, spreading and migration. CD63 Protein, Human/Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived CD63 protein, expressed by HEK293 , with C-His labeled tag.

Description

The CD63 protein serves as a cell surface receptor for TIMP1 and is critical for activating signaling cascades. It contributes to ITGB1 and integrin signaling, activating AKT, FAK/PTK2 and MAP kinases to promote cell survival, cytoskeletal reorganization, adhesion, spreading and migration. CD63 Protein, Human/Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived CD63 protein, expressed by HEK293 , with C-His labeled tag.

Background

CD63 protein serves as a cell surface receptor for TIMP1, playing a crucial role in the activation of cellular signaling cascades. It contributes to the activation of ITGB1 and integrin signaling, leading to the activation of AKT, FAK/PTK2, and MAP kinases. Its involvement promotes cell survival, actin cytoskeleton reorganization, cell adhesion, spreading, and migration by activating AKT and FAK/PTK2. CD63 is also implicated in VEGFA signaling through its regulation of KDR/VEGFR2 internalization. Additionally, it plays a role in intracellular vesicular transport processes and is essential for the normal trafficking of the PMEL luminal domain, crucial for melanocyte development and maturation. CD63 is further involved in leukocyte adhesion to endothelial cells by regulating SELP trafficking. While it may participate in mast cell degranulation in response to Ms4a2/FceRI stimulation, its role in degranulation in response to other stimuli remains limited. CD63 interacts with TIMP1 and ITGB1, recruiting TIMP1 to ITGB1, forms a complex with CD9 and ITGB3, and interacts with PMEL, KDR/VEGFR2, and SYT7.

Biological Activity

Measured by its binding ability in a functional ELISA. Immobilized Human BST2 at 2.5μg/mL (100μL/well) can bind Cynomolgus CD63. The ED50 for this effect is 2.509 μg/mL.

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

Lyophilized powder

Formulation

Lyophilized from a 0.2 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
