Stem Cell Factor Protein, Recombinant human

半岛bd体育手机客户端 说明

一般描述

Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. SCF stimulates the proliferation of myeloid, erythroid, and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors. Recombinant human SCF is an 18.4 kDa protein containing 165 amino acid residues corresponding to the soluble secreted form of SCF.
Product Source: E.coli

应用

For most in vitro applications, SCF exerts its biological activity in the concentration range of 0.2 to 20.0 ng/mL. Responding cells are (partial list): Stem cells, BM precursor cells.

外形

The sterile filtered solution was lyophilized from 10mM Acetic acid.

储存及稳定性

The lyophilized powder, though stable for a few weeks at room temperature, is best stored at -20°C. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. This solution can be further diluted into other aqueous buffers and stored at 2-8°C for 1 week or -20°C for future use. Reconstituted SCF should be stored in undiluted aliquots at -20°C. Avoid repeated freeze/thaw cycles.

分析说明

Specific Activity: Chemicon′s human SCF is fully biologically active when compared to standards.The ED50 was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is ≤ 2 ng/mL
