产品描述	Complement Component 1, q subcomponent (C1q) associates with C1r and C1s in order to yield the first component of the serum complement system. Deficiency of C1q has been associated with lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains: six A-chains, six B-chains, and six C-chains. Southern blot analysis of chromosomal DNA from vertebrate species demonstrated highest similarity between the C1qB genes, followed by C1qC and finally C1qA. Sequence comparison of C1q from three different species have shown that the B chains have the strongest similarity. C1q was already present at embryonic day 14 (E14) and showed little change in abundance through six weeks postnatal. At E16, C1qB mRNA was present at high abundance in putative microglia/macrophages in cortical marginal and intermediate zones, and hippocampal analge.
生物活性	Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first.

种属	Human
表达系统	Baculovirus Insect Cells
标签	C-His
蛋白编号	P02746
蛋白构建	A DNA sequence encoding the human C1QB (NP_000482.3) precursor (Met 1-Ala 253) was expressed, with a carboxy-terminal polyhistidine tag. Predicted N terminal: Gln 28
蛋白纯度	≥ 90 % as determined by SDS-PAGE
蛋白性状	Lyophilized powder
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing 50 mM Tris, 100 mM NaCl, 10% Glycerol, 0.5 mM TCEP, pH 7.5. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
别名	complement component 1, q subcomponent, B chain, C1QB
内毒素	< 1.0 EU/μg of the protein as determined by the LAL method.

化学信息

分子量	25.2 kDa (predicted); 30 kDa (reducing condition, due to glycosylation)

储存&溶解度

运输方式	In general, Lyophilized powders are shipping with blue ice.
存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
