Endothelial Cell Growth Supplement

(ECGS)
From Bovine Hypothalamus
Lyophilized from sodium chloride buffer containing streptomycin sulfate
Activity: promotes the growth of Fetal Bovine Heart Endothelial Cells (FBHEC) in 10% newborn calf serum when reconstituted at a concentration of 50-150 μg/ml serum-free medium.
It contains several growth factors (e.g. FGF, ECGF-α) and supports the growth of vascular endothelial cells from human and other mammalian species. Also, it may be used for the cloning and proliferation of hybridomas and human keratinocytes.
Each lot is sterile filtered and tested for bacteria, fungi, and mycoplasma contamination. Some cells may require supplementation with 1-100 μg/ml heparin.

Epidermal Growth Factor 95%

Epidermal growth factor or EGF is a growth factor isolated from mouse submaxillary glands that stimulates cell growth, proliferation, and differentiation by binding to its receptor EGFR. EGF is mitogenic for a variety of epidermal and epithelial cells, including fibroblasts, glial cells, mammary epithelial cells, vascular and corneal endothelial cells, bovine granulosa, rabbit chondrocytes, HeLa and SV40-3T3 cells.

Hybridoma Cell Growth Supplement

(HCGS)
From Cultured Human Endothelial Cells
HCGS will significantly improve the hybridoma cell cloning efficiency while eliminating feeder cell need.
HCGS may be used in dilutions of 1:5 to 1:10 (v/v). We recommend HCGS be thawed and sterile filtered (0.22 or 0.45 membrane) immediately prior to use.

Interleukin-2, Human, Natural

Human Interleukin-2 (IL-2), or Human T-cell growth factor is a glycoprotein which promotes in-vitro proliferation and long-term growth of T-cell lymphokines. Additionaly, IL-2 stimulates production of cytotoxic lymphocytes, natural killer cells, and lymphokine-activated killer cells.

Endothelial Cell Growth Supplement

(ECGS)
From Bovine Brain
Lyophilized powder with streptomycin sulfate.
ECGS is a broad culture medium growth supplement containing several growth factors which supports the growth of mammalian vascular endothelial cells and can be used in replacement of cell feeder layers in support of hybridoma clonal growth. It is isolated from bovine brain by a modification of the method of Maciag.
