Hemopexin Protein, Human (HEK293, C-His)

Cat. No.: HY-P70244A
COA Handling Instructions

Hemopexin Protein efficiently binds and transports heme to the liver for degradation, recovering iron. After this essential process, Hemopexin seamlessly re-enters circulation. It also interacts with FLVCR1, playing a multifaceted role in heme metabolism and iron homeostasis. Hemopexin Protein, Human (HEK293, His) is the recombinant human-derived Hemopexin protein, expressed by HEK293 , with C-6*His labeled tag.

Description

Hemopexin Protein efficiently binds and transports heme to the liver for degradation, recovering iron. After this essential process, Hemopexin seamlessly re-enters circulation. It also interacts with FLVCR1, playing a multifaceted role in heme metabolism and iron homeostasis. Hemopexin Protein, Human (HEK293, His) is the recombinant human-derived Hemopexin protein, expressed by HEK293 , with C-6*His labeled tag.

Background

Hemopexin Protein efficiently binds heme, facilitating its transport to the liver for degradation and subsequent recovery of iron. Once this crucial process is complete, the liberated hemopexin seamlessly re-enters circulation. Additionally, it engages in interactions with FLVCR1, contributing to its multifaceted role in heme metabolism and iron homeostasis.

Biological Activity

Measured by its ability to bind protoporphyrin IX (PPP-IX). Recombinant Human Hemopexin binds 42.85 μM PPP-IX, resulting in a 50% decrease in the fluorescence signal of rhHemopexin.

Molecular Weight

Approximately 60-90 kDa due to the glycosylation.

Purity

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

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

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).

Storage & Stability

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.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
