Description

LAMP3/CD208 is a lysosomal glycoprotein that participates in the unfolded protein response (UPR) and contributes to protein degradation and cell survival, especially in the presence of proteasome dysfunction.It crucially promotes lysosome-autophagosome fusion and regulates autophagy.LAMP3/CD208 Protein, Human (HEK293, His) is the recombinant human-derived LAMP3/CD208 protein, expressed by HEK293 , with C-His labeled tag.

Background

LAMP3/CD208, a lysosomal membrane glycoprotein, is involved in the unfolded protein response (UPR), contributing to protein degradation and cell survival particularly during proteasomal dysfunction. Additionally, it plays a crucial role in the fusion process between lysosomes and autophagosomes, thereby modulating autophagy. LAMP3/CD208 has been identified as a promoter of hepatocellular lipogenesis through the activation of the PI3K/Akt pathway. Furthermore, it is implicated in dendritic cell function and adaptive immunity. In the context of microbial infection, LAMP3/CD208 plays a positive role in post-entry steps of influenza A virus replication, influencing processes such as virus uncoating, cytosolic transport, or nuclear import of viral components, and contributing to the nuclear accumulation of influenza nucleoprotein/NP during the early stages of viral infection.

Biological Activity

Measured by its ability to enhance MDA-MB-231 cells migration. The ED50 for this effect is 0.401μg/mL, corresponding to a specific activity is 2.494×103 U/mg.

Glycosylation
Yes
Purity
  • ≥ 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 from date of receipt. 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.

  • 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)
× = ×

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
