ITIH3 Protein, Human (HEK293, His)

The ITIH3 protein has a dual role: as a carrier of hyaluronic acid in serum and as a binding protein that facilitates interactions with various matrix proteins. These interactions regulate the localization, synthesis, and degradation of hyaluronic acid, which is critical for multiple cellular activities. ITIH3 Protein, Human (HEK293, His) is the recombinant human-derived ITIH3 protein, expressed by HEK293 , with C-6*His labeled tag.

The ITIH3 protein exhibits a versatile role, potentially acting as a carrier for hyaluronan in serum and serving as a binding protein that facilitates interactions between hyaluronan and various matrix proteins, including those present on cell surfaces in tissues. These interactions play a pivotal role in regulating the localization, synthesis, and degradation of hyaluronan, processes essential for cells undergoing diverse biological activities. Within the context of I-alpha-I plasma protease inhibitors, ITIH3 contributes to the assembly of these inhibitors, forming complexes with one or two heavy chains (HC) and the light chain bikunin. Notably, the pre-alpha-inhibitor (P-alpha-I) consists of ITIH3/HC3 and bikunin, highlighting the integral involvement of ITIH3 in the structural composition of these plasma protease inhibitors.

Approximately 90.0 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 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).

Stored at -20°C for 2 years. 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.

Room temperature in continental US;may vary elsewhere.
