Sheep Prolactin Protein
Recombinant of sheep Prolactin protein
Product Specifications
Product Name Alternative
Mammotropin, Luteotropic hormone, Luteotropin, PRL.
Source
Escherichia Coli
Purity
Greater than 99.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
Bioactivity
Is fully biologically active as evidenced by inducing proliferation of Nb2 cells.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
It is recommended to reconstitute the lyophilized Prolactin in sterile 18MΩ-cm H2O or 0.4% NaHCO3 adjusted to pH 8-9, not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Storage Conditions
Stability: Lyophilized Prolactin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Prl 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
Notes
For research use only.
Applications Notes
Protein content: Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.93 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC DNAman computer analysis program of protein sequences
Preservative
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3.
AA Sequence
The sequence of the first six N-terminal amino acids was determined and was found to be Ala-Thr-Pro-Val-Cys-Pro
