WIF-1 Protein, Human (HEK293, His)

Cat. No.: HY-P70982
COA Handling Instructions

WIF-1 protein critically binds to WNT protein, inhibits its activity and regulates the WNT signaling pathway. In addition to its inhibitory role, WIF-1 may also contribute to mesoderm segmentation, implicating its role in embryonic development. WIF-1 Protein, Human (HEK293, His) is the recombinant human-derived WIF-1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of WIF-1 Protein, Human (HEK293, His) is 351 a.a., with molecular weight of 42-48 kDa.

Background

The WIF-1 protein plays a crucial role as it binds to WNT proteins, effectively inhibiting their activities. This interaction suggests a pivotal regulatory function in WNT signaling pathways. Beyond its inhibitory role, WIF-1 may also be involved in mesoderm segmentation, hinting at its potential contributions to embryonic development. Furthermore, WIF-1 interacts with MYOC, indicating a possible association with additional cellular processes or signaling cascades. The multifaceted interactions of WIF-1 underscore its importance in modulating WNT-mediated activities and its potential involvement in broader developmental and cellular events.

Molecular Weight

Approximately 42-48 kDa

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

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of 10 mM HAc-NaAc, 150 mM NaCl, 0.5% CHAPS, pH 4.0 or 50 mM Tris-HCL, 300 mM NaCl, pH 7.4.

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.

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
