About this protein
Name
Recombinant Human M-CSF (Recombinant Human Macrophage Colony Stimulating Factor; rHuM-CSF)；重組人巨噬細(xì)胞集落刺激因子
Synonyms
CSF1; CSF-1; colony stimulating factor 1 (macrophage); CSF-1; Lanimostim; macrophage colony stimulating factor; macrophage colony-stimulating factor 1; M-CSF; MCSFlanimostim; MGC31930
Purity
>95% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine M-NFS-60 cells is less than 1ng/ml, corresponding to a specific activity of >1.0×106IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered solution in PBS, pH7.4.
Endotoxin
Less than 1EU/μg of rHuM-CSF as determined by LAL method.
Reconstitution
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 0.1mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.
Category
Cytokine
Background
Macrophage Colony Stimulating Factor (M-CSF), also named CSF-1, is a hematopoietic growth factor that is involved in the proliferation, differentiation, and survival of monocytes, macrophages, and bone marrow progenitor cells. It is produced by osteoblasts (as a result of endocrine stimulation by parathyroid hormone) exerts paracrine effects on osteoclasts and can interact with CSF1R. M-CSF is a four α-helical bundle cytokine and its active form is found extracellularly as a disulfide-linked homodimer. Four transcript variants encoding three different isoforms have been reported for M-CSF gene. Although forms may vary, all of them contain the N-terminal 150a.a. portion that is necessary and sufficient for interaction with the receptor. The first 223a.a. of mature human M-CSF shares 88%, 86%, 81% and 74% sequence identity with corresponding regions of dog, cow, mouse and rat M-CSF, respectively. Human M-CSF is active in the mouse, but mouse M-CSF is reported to be species-specific.

保存條件: -20℃或更低溫度保存，至少一年有效。由于蛋白的每次凍融均會(huì)引起部分失活，所以**配制成相應(yīng)濃度的儲(chǔ)存液后(請(qǐng)根據(jù)產(chǎn)品簡(jiǎn)介中Reconstitution一欄的信息配制儲(chǔ)存液)，須分裝后-20℃或更低溫度凍存，以避免反復(fù)凍融。 注意事項(xiàng): 由于有些塑料管壁對(duì)某些蛋白有較強(qiáng)的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein，如0.1% BSA等)的主要作用是預(yù)先封閉塑料管壁上的蛋白結(jié)合位點(diǎn)，使細(xì)胞因子或重組蛋白不會(huì)粘附于管壁。所以一定要使用產(chǎn)品簡(jiǎn)介中Reconstitution一欄的信息配制儲(chǔ)存液。 本產(chǎn)品**于專業(yè)人員的科學(xué)研究用，不得用于臨床診斷或**，不得用于食品或藥品，不得存放于普通住宅內(nèi)。 為了您的**和健康，請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
