  2. MME Protein, Human (HEK293, Tag Free)

MME proteins exhibit thermolysin-like specificity and primarily degrade polypeptides of up to 30 amino acids. Crucially, it plays a key role in cleaving the Gly-Phe bond to degrade opioid peptides, including Met-enkephalin and Leu-enkephalin. MME Protein, Human (HEK293) is the recombinant human-derived MME protein, expressed by HEK293 , with tag free. The total length of MME Protein, Human (HEK293) is 699 a.a., with molecular weight of 80-100 kDa.

Description

MME proteins exhibit thermolysin-like specificity and primarily degrade polypeptides of up to 30 amino acids. Crucially, it plays a key role in cleaving the Gly-Phe bond to degrade opioid peptides, including Met-enkephalin and Leu-enkephalin. MME Protein, Human (HEK293) is the recombinant human-derived MME protein, expressed by HEK293 , with tag free. The total length of MME Protein, Human (HEK293) is 699 a.a., with molecular weight of 80-100 kDa.

Background

The MME Protein demonstrates a thermolysin-like specificity, predominantly acting on polypeptides of up to 30 amino acids. Biologically crucial, it plays a key role in the degradation of opioid peptides, including Met- and Leu-enkephalins, achieved through the cleavage of a Gly-Phe bond. Additionally, MME catalyzes the cleavage of bradykinin, substance P, and neurotensin peptides and is capable of cleaving angiotensin-1, angiotensin-2, and angiotensin 1-9. The protein is involved in the degradation of atrial natriuretic factor (ANF) and brain natriuretic factor (BNP(1-32)). Furthermore, MME displays UV-inducible elastase activity toward skin preelastic and elastic fibers.

Molecular Weight

Approximately 80-105 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.

  • Reconstitution Calculator

  • 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)
× = ×
C1   V1   C2   V2

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
