Introduction
Growth hormone (GH) is part of the somatotropin/prolactin hormone family, essential for growth regulation. This gene, along with four others, forms the growth hormone locus on chromosome 17. Their shared transcriptional orientation suggests evolutionary gene duplication. These five genes exhibit significant sequence similarity. Alternative splicing further diversifies the five growth hormones, potentially leading to specialized functions. This specific family member is expressed in the pituitary, unlike the other four genes in the growth hormone locus, which are also found in placental tissue. Mutations or deletions within this gene can result in growth hormone deficiency and short stature.
Description
Recombinant Growth Hormone Mahi Mahi, produced in E. coli, is a single, non-glycosylated polypeptide chain. It consists of 190 amino acids, with a molecular weight of 21.81 kDa. Purification of GH is achieved using proprietary chromatographic methods.
Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation
The protein was lyophilized from a 1 mg/ml solution containing 0.0045 mM NaHCO3.
Solubility
Reconstitute the lyophilized Growth Hormone Mahi Mahi with sterile 18 MΩ-cm H2O to a concentration of at least 100 µg/ml. This solution can be further diluted with other aqueous solutions.
Stability
Lyophilized Growth Hormone Mahi Mahi is stable at room temperature for up to 3 weeks. However, it's recommended to store it desiccated below -18°C. After reconstitution, GH Mahi Mahi remains stable at 4°C for 2-7 days. For long-term storage, freeze at -18°C. Adding a carrier protein (0.1% HSA or BSA) is suggested for long-term storage. Avoid repeated freeze-thaw cycles.
Purity
Purity exceeds 97.0% as determined by:
(a) SEC-HPLC analysis.
(b) SDS-PAGE analysis.
Synonyms
GH1, GH, GHN, GH-N, hGH-N,Pituitary growth hormone, Growth hormone 1, Somatotropin.
