点击次数：3879 发布时间：2018/11/26 8:50:20
产品描述:
Macrophage Colony Stimulating Factor (M-CSF), also known as CSF-1, is a four α helical bundle cytokine that is the primary regulator of macrophage survival, proliferation ａnd differentiation. M-CSF is also essential for the survival ａnd proliferation of osteoclast progenitors. M-CSF also primes ａnd enhances macrophage killing of tumor cells ａnd microorganisms, regulates the release of cytokines ａnd other inflammatory modulators from macrophages, ａnd stimulates pinocytosis.
表达系统 :
Baculovirus infected Silkworm
溶解方法:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water to a concentration of 0.1 mg/mL. Stock solutions should be apportioned into working aliquots ａnd stored at < -20°C Further dilutions should be made in appropriate buffered solutions.
产品组成:
Lyophilized from a 0.2 μm filtered solution in 20 mM PB, containing 1% HSA ａnd 3% Mannitol.
存储条件:
This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots ａnd store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
分子量:
As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 42.0 ± 4.2 kDa in SDS-PAGE, a covalently linked homodimer, of two 21 kDa polypeptide monomers.
内毒素:
Less than 1 EU/μg of M-CSF as determined by LAL method.
产品用途:
This material is offered by Cyagen Biosciences for research, laboratory or further evaluation purposes. FOR RESEARCH USE ONLY. NOT INTENDED FOR ANY ANIMAL OR HUMAN THERAP EUTIC OR DIAGNOSTIC USE.
生物学活性:
The ED50 determined by a cell proliferation assay using murine M-NFS-60 cells is less than 1 ng/mL, corresponding to a specific activity of > 1.0 × 106 IU/mg.
产品形态:
Sterile filtered white lyophilized (freeze-dried) powder.
