SHH Protein, Mouse (C25II)

SHH Protein, Mouse (C25II) is a recombinant mouse sonic hedgehog variant.

Sonic Hedgehog (SHH) is a secreted factor. The protein is heavily modified through cleavage and posttranslational modification and its release from producing cells can also be modulated by interactions with Dispatched, Scube2, and heparan sulfate proteoglycan. Sonic hedgehog (SHH) is the main ligand of hedgehog (Hh) pathway in mouse^[1][2].

The ED₅₀ is <2 μg/mL as measured by C3H/10T1/2 (CCL-226) cells, corresponding to a specific activity of >500 units/mg.

• 
  Measured by its ability to induce alkaline phosphatase production by C3H10T1/2 mouse embryonic fibroblast cells. The ED₅₀ for this effect is 0.0797 µg/mL.

Approximately 20 kDa, based on SDS-PAGE under reducing conditions.

• 
  ≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized after extensive dialysis against PBS, pH 7.4.

<0.2 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 from date of receipt. 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.
