Description

APRIL Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 146 amino acids and having a molecular mass of 16.4 kDa. The APRIL is purified by proprietary chromatographic techniques.

Product Specs

Introduction
APRIL, a member of the TNF ligand superfamily (TNFSF13), is a type II transmembrane protein. APRIL expression is typically low in tissues but increases in various tumor types and transformed cell lines. APRIL promotes the proliferation of tumor cell lines and enhances tumorigenicity in nude mice.
Description
Recombinant Mouse APRIL, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 146 amino acids with a molecular weight of 16.4 kDa. The APRIL protein undergoes purification using proprietary chromatographic methods.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2 µm filtered solution in phosphate-buffered saline (PBS), pH 7.4, containing 0.02% Tween-20.
Solubility
To reconstitute the lyophilized APRIL, it is advised to dissolve it in sterile 18 MΩ-cm H₂O at a concentration of at least 100 µg/ml. This solution can be further diluted in other aqueous solutions.
Stability
Lyophilized APRIL remains stable at room temperature for up to three weeks; however, it is recommended to store it desiccated below -18°C. After reconstitution, store APRIL at 4°C for 2-7 days. For long-term storage, freeze APRIL below -18°C. The addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Avoid repeated freeze-thaw cycles.
Purity
Purity exceeds 97.0%, as determined by SDS-PAGE analysis.
Biological Activity
Biological activity is assessed through a cell proliferation assay using activated T cells.
Synonyms
Tumor necrosis factor ligand superfamily member 13, A proliferation-inducing ligand, APRIL, CD256, Tnfsf13, April.

Product Science Overview

Structure and Synthesis

APRIL is synthesized as a 32 kDa proprotein, which is cleaved by furin in the Golgi apparatus to release the active 17 kDa soluble molecule . The recombinant mouse APRIL protein is typically produced in yeast or Chinese Hamster Ovary (CHO) cell lines .

Biological Functions

APRIL has been shown to:

  • Protect cells from apoptosis: It helps in preventing programmed cell death, thereby promoting cell survival .
  • Promote B cell development: APRIL is essential for the maturation and function of B cells, which are crucial components of the adaptive immune system .
Applications

Recombinant mouse APRIL is widely used in research for:

  • Cell culture: It serves as a standard in ELISA assays and as a control in Western blotting .
  • Immunological studies: Researchers use it to study the mechanisms of immune responses and the role of APRIL in various diseases .
Storage and Stability

The recombinant protein is typically lyophilized and should be reconstituted in deionized water. It is stable for up to 12 months when stored at -20 to -70°C and should be handled under sterile conditions to avoid contamination .
