abm | Immortalized Rat Steroidogenic Granulosa Cells stably expressing LH/CG Receptor (GLHR-15) | T0606

in vitro culture of primary cells.

The Immortalized Rat Steroidogenic Granulosa Cells stably expressing LH/CG Receptor is responsive to luteinizing hormone (LH) or choriogonadtropin (hCG) stimulation and produces progesterone and 20α-OH-P as a result at levels comparable to primary cells. This cell line is useful in studying molecular mechanisms associated with gonadotropin stimulated steroidogenesis. Together with the Immortalized Rat Steroidogenic Granulosa Cells expressing FSH Receptor (Cat. No T0605), researchers can compare the LH and FSH signaling in homologues cell systems.

Propagation:

The base medium for this cell line is Prigrow IV medium available at abm . To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10% and Penicillin/Streptomycin Solution to a final concentration of 1%
Carbon dioxide (CO₂): 5%, Temperature: 37.0°C.

Quality Control:

1) Phenotypic response to hCG stimulation was characterized by shape changes (cells rounding up as a result of intracellular cAMP accumulation); 2) LH/CG receptor expression was measured by radiolabelled 125I-hCG binding assay- the cells express 19,000 FSH receptors/cell with a Kd of 180 pM, similar to the native receptor; 3) Production of progesterone and 20α-OH-P was determined by radioimmunoassay (RIA); 4) Production of cAMP was measured by a protein binding method
