Product Specs

Introduction
RELM-beta, or Resistin-Like Molecule-beta, belongs to a family of secreted proteins characterized by a conserved cysteine-rich C-terminus. This family includes resistin (FIZZ3), RELM-alfa (FIZZ1), RELM-beta (FIZZ2), and RELM-gamma. While humans only possess resistin and RELM-beta, rodents express all four. Produced exclusively by intestinal goblet cells, RELM-beta is abundant in stool. Interestingly, RELM-beta is absent in the stool of germ-free mice until they are introduced to bacteria from a pathogen-free environment. Certain colon carcinoma cell lines secrete RELM-beta into cell culture supernatant. The exact function of RELM-beta remains unclear. However, high doses of recombinant RELM-beta in mice have been linked to hyperglycemic effects, such as decreased glucose disposal and increased hepatic glucose production.
Description
Recombinant Mouse RELM-b, produced in E. coli, is a monomeric, non-glycosylated polypeptide chain with 83 amino acids and a molecular weight of 8.9 kDa. Purification of Mouse RETNLB is achieved using proprietary chromatographic techniques.
Physical Appearance
Lyophilized powder with a brownish hue.
Formulation
The protein was lyophilized from a 1 mg/ml solution containing 10 mM Acetic Acid and a 2:1 ratio of mannitol to protein.
Solubility
Reconstitute the lyophilized protein to a concentration of 0.1 mg/ml using sterile, pyrogen-free water.
Stability
Lyophilized RETNLB can be stored stably at -20°C. Upon reconstitution, maintain the protein at -20°C. For long-term storage, adding a carrier protein such as HSA or BSA (0.1%) is recommended.
Purity
Purity exceeds 97% as assessed by SDS-PAGE.

Product Science Overview

Structure and Expression

RELM-β is a non-glycosylated protein consisting of 83 amino acids, with a molecular weight of approximately 8.9 kDa . It is expressed primarily in the colon and small intestine . The protein is secreted by intestinal goblet cells and its secretion is induced by Th2 cytokines in response to nematode infections .

Biological Function

RELM-β plays a significant role in the immune response, particularly in the context of parasitic infections. It is involved in the regulation of inflammation and has been shown to be upregulated in various inflammatory conditions . The protein’s function is closely related to its ability to form homodimers, which are essential for its biological activity .

Recombinant Production

Recombinant mouse RELM-β is typically produced in Escherichia coli and is available as a sterile filtered, lyophilized powder . The recombinant protein is often used in research to study its role in inflammation and immune response. It is important to handle the reconstituted protein with care, ensuring it is aliquoted and stored at -20°C to maintain its stability .

Applications in Research

RELM-β is used in various research applications, including studies on inflammation, immune response, and parasitic infections. Its role in these processes makes it a valuable tool for understanding the mechanisms underlying these conditions and for developing potential therapeutic strategies .
