Handling Instructions

Molarity Calculator

IGF-I (24-41) (Insulin-like Growth Factor I (24-41)) TFA is amino acids 24 to 41 fragment of IGF-I. IGF-I TFA, a 70 aa polypeptide hormone, is a trophic factor for both neurons and glial cells. IGF-I TFA is partly responsible for systemic growth hormone (GH) activities. IGF-I TFA has anabolic, antioxidant, anti-inflammatory and cytoprotective actions. IGF-I (24-41) TFA regulates somatic growth and behavioral development.

Description

IGF-I (24-41) (Insulin-like Growth Factor I (24-41)) TFA is amino acids 24 to 41 fragment of IGF-I. IGF-I TFA, a 70 aa polypeptide hormone, is a trophic factor for both neurons and glial cells. IGF-I TFA is partly responsible for systemic growth hormone (GH) activities. IGF-I TFA has anabolic, antioxidant, anti-inflammatory and cytoprotective actions. IGF-I (24-41) TFA regulates somatic growth and behavioral development[1][2][3].

In Vivo

IGF-I (24-41) TFA (ICV; 200 ng dose; 2 µL; postnatal days (PND) 2, 4, and 7) regulates somatic growth and behavioral development[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Peptide Solubility and Storage Guidelines:

1.  Calculate the length of the peptide.

2.  Calculate the overall charge of the entire peptide according to the following table:

  Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.  Recommended solution:

Overall charge of peptide Details
Negative (<0) 1.  Try to dissolve the peptide in water first.
2.  If water fails, add NH4OH (<50 μL).
3.  If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>0) 1.  Try to dissolve the peptide in water first.
2.  If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.  If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.  Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.  For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.

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.
