PGLYRP4/PGRP-I beta Protein, Human (HEK293, His)

Cat. No.: HY-P77137
COA Handling Instructions

PGLYRP4/PGRP-I beta protein is a model receptor that binds to the cell wall peptide peptidoglycan (PGN) in Gram-positive bacteria and exerts bactericidal activity by interfering with peptidoglycan biosynthesis. Its antimicrobial properties extend to Gram-negative bacteria, although it also binds to them. PGLYRP4/PGRP-I beta Protein, Human (HEK293, His) is the recombinant human-derived PGLYRP4/PGRP-I beta protein, expressed by HEK293 , with C-His labeled tag.

Description

PGLYRP4/PGRP-I beta protein is a model receptor that binds to the cell wall peptide peptidoglycan (PGN) in Gram-positive bacteria and exerts bactericidal activity by interfering with peptidoglycan biosynthesis. Its antimicrobial properties extend to Gram-negative bacteria, although it also binds to them. PGLYRP4/PGRP-I beta Protein, Human (HEK293, His) is the recombinant human-derived PGLYRP4/PGRP-I beta protein, expressed by HEK293 , with C-His labeled tag.

Background

PGLYRP4/PGRP-I beta Protein, a pattern receptor, exhibits binding affinity to murein peptidoglycans (PGN) found in Gram-positive bacteria, showcasing bactericidal activity against this bacterial group. Its antimicrobial properties may be attributed to its interference with peptidoglycan biosynthesis, leading to the killing of Gram-positive bacteria. Additionally, PGLYRP4/PGRP-I beta demonstrates bacteriostatic activity against Gram-negative bacteria, despite also binding to this bacterial class. As part of innate immunity, this protein plays a crucial role in recognizing and responding to bacterial pathogens. It forms homodimers connected by disulfide bonds and can heterodimerize with PGLYRP3, further expanding its functional repertoire in host defense mechanisms.

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
