Product Specs

Introduction
Indian Hedgehog (IHH) is a signaling protein belonging to the Hedgehog family, crucial for various developmental processes, including growth, patterning, and morphogenesis. In vertebrates, the Hedgehog family comprises proteins like Sonic Hedgehog (Shh), Desert Hedgehog (Dhh), and IHH. Specifically, IHH plays a vital role in bone growth and differentiation, and yolk sac vasculogenesis, particularly in differentiating epiblast cells into endothelial and red blood cells. IHH mRNA expression is observed in fetal organs like the lung, gut, stomach, liver, kidney, pancreas, and significantly in cartilage within growth regions of developing bone. Mutations in the IHH gene can lead to brachydactyly type A1, characterized by shortened or malformed phalanges, and acrocapitofemoral dysplasia.
Description
Recombinant Mouse IHH, produced in E. coli, is a single, non-glycosylated polypeptide chain comprising 176 amino acids, resulting in a molecular mass of 19.8 kDa. The purification process of IHH involves proprietary chromatographic techniques.
Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation
Lyophilized from a 0.2 µm filtered concentrated solution in 1X PBS, with a pH of 7.4.
Solubility
For reconstitution, it is recommended to dissolve the lyophilized IHH in sterile 18 MΩ-cm H₂O at a concentration not less than 100 µg/ml. Further dilutions can be made using other aqueous solutions.
Stability
Lyophilized IHH remains stable at room temperature for up to 3 weeks; however, it is advisable to store it desiccated below -18°C. After reconstitution, IHH should be stored at 4°C for 2-7 days. For long-term storage, freezing below -18°C is recommended. It is advisable to add a carrier protein (0.1% HSA or BSA) for long-term storage and avoid repeated freeze-thaw cycles.
Purity
The purity is determined to be greater than 95.0% through the following analyses: (a) RP-HPLC analysis and (b) SDS-PAGE analysis.
Biological Activity

The biological activity is assessed based on the ability to induce alkaline phosphatase production in C3H/10T1/2 (CCL-226) cells. The anticipated ED₅₀ for this effect falls within the range of 3.0-10.0 µg/ml, which corresponds to a specific activity of 100-334 units/mg.

Product Science Overview

Introduction

Indian Hedgehog (Ihh) is a crucial signaling protein that belongs to the Hedgehog family, which also includes Sonic Hedgehog (Shh) and Desert Hedgehog (Dhh). These proteins play significant roles in embryonic development and are highly conserved across species .

Discovery and Gene Encoding

The Hedgehog (hh) gene was initially identified in Drosophila as a segment polarity gene. Vertebrate homologues of Hh, including Ihh, were later discovered. Ihh is encoded by the Ihh gene and is involved in various developmental processes .

Expression Patterns and Tissue Distribution

Ihh mRNA expression is detected in several fetal tissues, including the lung, gut, stomach, liver, kidney, pancreas, and cartilage, particularly in the growth regions of developing bones . In adults, Ihh is expressed in the kidney and liver .

Biological Functions

Ihh plays a pivotal role in regulating the rate of chondrocyte proliferation and differentiation, which is essential for bone growth and development . It also acts as an antagonist of the Wnt signaling pathway in colon cancers .

Recombinant Ihh Protein

Recombinant Ihh protein is typically produced in E. coli and is supplied in a lyophilized form. It is used in various research applications to study its biological functions and signaling pathways .
