Available Options

Select the variant that best fits your experiment. Availability and lead time may vary by option.

  • Options: Size (3) — 10 ug, 50 ug, 1 mg
  • Lead time: options listed as “in stock at manufacturer” typically ship in 5–7 business days; other statuses may take longer.
  • Storage: Lyophilized IGF1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
  • Shipping: cold-chain shipment (typically with ice packs).
  • Upon receipt: store at the recommended temperature as soon as possible.
  • Sales terms and conditions: Please review prior to ordering.
Field Specification
Mfr No cyt-295
Alternative Names Somatomedin C, IGF-I, IGFI.
Biological Activity Binding assays of the 125I-Gealthead Seabream IGF1 to Gilthead Seabream or carp (Cyprinus carpio) sera resulted in high specific binding, indicating the existence of one or more IGF-binding proteins. In binding experiments to crude Gilthead Seabream brain homogenate, using human<br>(h) IGF-I as a ligand, the respective IC50 value of hIGF1 was about fourfold lower than that of Gilthead Seabream IGF-1. Recombinant Gilthead Seabream IGF-1 exhibited mitogenic activity in a mouse mammary gland-derived MME-L1 cell line which was approximately 200-fold lower than that of hIGF1. Binding experiments to intact MME-L1 cells suggests that this difference most likely results from a correspondingly lower affinity for IGF1 receptor in these cells. In contrast, the activities of Gilthead Seabream IGF-I and hIGF-I measured by 35S uptake by gill arches from the goldfish (Carassius auratus) were identical, indicating that the recombinant Gilthead Seabream IGF-I is biologically active.
Concentration 1 mg/ml
Expression System
  • E. coli
Form Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02% NaHCO3.
Product Type
  • Proteins & Peptides
  • Cytokines and Growth Factors
Protein Length 68
Purity Greater than 98.0% as determined by:<br>(a) Analysis by SEC-HPLC.<br>(b) Analysis by SDS-PAGE.
Solubility It is recommended to reconstitute the lyophilized IGF-1 in sterile 0.4% NaHCO3 adjusted to ph 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Source Escherichia Coli.
Storage Lyophilized IGF1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Target IGF1

Recombinant Gilthead Seabream Insulin Like Growth Factor-1 is supplied as a recombinant protein for in vitro research use.

Background

The somatomedins, or IGFs, comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of GH. Early studies showed that GH did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as somatomedin. Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2), and somatomedin B.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

Quality notes

Somatomedin C quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.60 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of IGF1 as a Reference Standard.

What is the purity of Recombinant Gilthead Seabream Insulin Like Growth Factor-1?
Greater than 98.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02% NaHCO3. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Gilthead Seabream Insulin Like Growth Factor-1 be stored?
Lyophilized IGF1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in E. coli. The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
