Animal-Free HDGF Protein, Human (His)

Customer Review

Based on 1 Customer Validation

The HDGF protein acts as a transcriptional repressor and was previously thought to have mitogenic activity for fibroblasts and be a heparin-binding protein. However, recent studies have shown that it does not exhibit mitogenic activity for fibroblasts and does not bind heparin. Animal-Free HDGF Protein, Human (His) is the recombinant human-derived animal-FreeHDGF protein, expressed by E. coli , with C-His labeled tag.This product is for cell culture use only.

Biological Activity

Description

The HDGF protein acts as a transcriptional repressor and was previously thought to have mitogenic activity for fibroblasts and be a heparin-binding protein. However, recent studies have shown that it does not exhibit mitogenic activity for fibroblasts and does not bind heparin. Animal-Free HDGF Protein, Human (His) is the recombinant human-derived animal-FreeHDGF protein, expressed by E. coli , with C-His labeled tag.This product is for cell culture use only.

Background

Hepatoma-derived growth factor (HDGF) exhibits a dual role as both a transcriptional repressor and a mitogenic factor for fibroblasts. While it acts as a repressor in transcriptional regulation, influencing cellular processes, it also demonstrates mitogenic activity, particularly for fibroblasts. HDGF has been identified as a heparin-binding protein, which suggests its involvement in interactions with heparin and potentially modulating cellular responses. However, it's noteworthy that conflicting reports exist, with some studies indicating that HDGF lacks mitogenic activity for fibroblasts and does not bind to heparin. These findings highlight the complexity of HDGF's functional repertoire, showcasing its diverse roles in transcriptional control, mitogenic signaling, and potential interactions with heparin.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, trehalose.

Endotoxin Level

<0.1 EU/μg, determined by LAL method.

Reconstitution

It is recommended to reconstitute to a concentration of 100-200 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
