LRRC15 Protein, Human (HEK293, His)

Cat. No.: HY-P72512
Handling Instructions

LRRC15 protein actively modulates SARS-CoV-2 infectivity by directly interacting with the spike protein, inhibiting ACE2(+) cell infection. While not an entry receptor, LRRC15, expressed on nearby cells, sequesters virions, and its direct interaction with the spike protein's RBD domain leads to virion sequestration at the cell surface. LRRC15 Protein, Human (HEK293, His) is the recombinant human-derived LRRC15 protein, expressed by HEK293 , with C-6*His labeled tag.

Description

LRRC15 protein actively modulates SARS-CoV-2 infectivity by directly interacting with the spike protein, inhibiting ACE2(+) cell infection. While not an entry receptor, LRRC15, expressed on nearby cells, sequesters virions, and its direct interaction with the spike protein's RBD domain leads to virion sequestration at the cell surface. LRRC15 Protein, Human (HEK293, His) is the recombinant human-derived LRRC15 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

The LRRC15 protein modulates the infectivity of SARS-CoV-2 by interacting with its spike protein. It does not function as an entry receptor for SARS-CoV-2, but instead, when expressed on nearby cells, it sequesters virions and inhibits SARS-CoV-2 infection of ACE2(+) cells in a trans manner. Furthermore, LRRC15 protein directly interacts with the RBD domain of the human coronavirus SARS-CoV-2 spike protein, leading to virion sequestration at the cell surface.

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
