PLAU/uPA Protein, Rat (HEK293, His)

Cat. No.: HY-P73561
COA Handling Instructions

PLAU/uPA proteins are characterized by a lack of conserved residues critical for feature annotation propagation, raising interesting questions about their structural and functional aspects. This uniqueness suggests potential differences in molecular interactions in plasminogen activation and fibrinolysis regulation. PLAU/uPA Protein, Rat (HEK293, His) is the recombinant rat-derived PLAU/uPA protein, expressed by HEK293 , with C-His labeled tag. The total length of PLAU/uPA Protein, Rat (HEK293, His) is 413 a.a., with molecular weight of 30-35 kDa.

Description

PLAU/uPA proteins are characterized by a lack of conserved residues critical for feature annotation propagation, raising interesting questions about their structural and functional aspects. This uniqueness suggests potential differences in molecular interactions in plasminogen activation and fibrinolysis regulation. PLAU/uPA Protein, Rat (HEK293, His) is the recombinant rat-derived PLAU/uPA protein, expressed by HEK293 , with C-His labeled tag. The total length of PLAU/uPA Protein, Rat (HEK293, His) is 413 a.a., with molecular weight of 30-35 kDa.

Background

PLAU, also known as uPA (urokinase-type plasminogen activator), is distinguished by the absence of conserved residue(s) necessary for the propagation of feature annotation. This unique characteristic raises intriguing questions about the structural and functional aspects of PLAU, suggesting potential distinctions in its molecular interactions within the context of plasminogen activation and the regulation of fibrinolysis. The absence of these conserved residues underscores the specific attributes of PLAU and underscores the need for in-depth investigations to elucidate its distinctive roles in cellular processes and pathological conditions.

Biological Activity

Human uPAR, hFc Tag captured on CM5 Chip via Protein A can bind Rat PLAU, His Tag with an affinity constant of 4.31 μM as determined in SPR assay (Biacore T200).

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

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.

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.

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
