Description

(D-Trp12,Tyr34)-pTH (7-34) amide (bovine) is a potent and competitive antagonist of parathyroid hormone (PTH), with a Ki of 69 nM in bovine renal cortical membrane. (D-Trp12,Tyr34)-pTH (7-34) amide (bovine) can be used for growth and development regulation[1][2].

IC50 & Target

Ki: 69 nM (PTH)[1]

In Vitro

(D-Trp12,Tyr34)-pTH (7-34) amide (0.05-10 μM) causes a concentration-dependent inhibition of PTHrP or PTH-stimulated cAMP formation in opossum kidney (OK) cells[2].
(D-Trp12,Tyr34)-pTH (7-34) amide (0.1-10 μM) attenuates inhibition of NapiT promoted by 1 nM of either PTHrP or PTH[2].

In Vivo

(D-Trp12,Tyr34)-pTH (7-34) amide (1 mg/mL once, 0.1 mg/mL for 6 h; i.v.) has no significant effect on serum calcium levels in hypercalcemic athymic nude mice bearing a human squamous cell carcinoma of the lung[3].

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.
