About this Antibody
Name Recombinant Human BD-1, 47a.a. (Recombinant Human β-defensin 1, 47a.a.; rHuBD-1, 47a.a.)；重组人β-防御素1，47a.a.
Synonyms Beta-defensin 1; BD-1; hBD-1; Defensin, beta 1; DEFB1; BD1; HBD1
Purity >98% by SDS-PAGE and HPLC analyses.
Biological Activity Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using CD34+ dendritic cells is in a concentration range of 100.0-1000.0ng/ml.
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.4, 130mM NaCl.
Endotoxin Less than 1EU/μg of rHuBD-1, 47a.a. 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 or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/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 Defensins (alpha and beta) are cationic peptides with antimicrobial activity against Gram-negative and Gram-positive bacteria, fungi, and enveloped viruses. They are 2-6kDa proteins and take important roles in innate immune system. On the basis of their size and pattern of disulfide bonding, mammalian defensins are classified into alpha, beta and theta categories. β-Defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. Four human β-defensins have been identified and they are expressed on some leukocytes and at epithelial surfaces. Because β-defensins is cationic peptides, they can therefore interact with the membrane of invading microbes, which are negative due to lipopolysaccharides (LPS) and lipoteichoic acid (LTA) found in the cell membrane. Especially, they have higher affinity to the binding site compared to Ca2+ and Mg2+ ions. Furthermore, they can affect the stability of the membrane. The β-defensin proteins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal sequence and, in the case of BD-1 (36a.a.), a propeptide region. Beta-defensin 1 may play a role in the pathogenesis of severe sepsis. Variation in human Beta Defensin-1 contributes to asthma diagnosis, with apparent gender-specific effects. Variation in human β-defensins 1 contributes to asthma diagnosis, with apparent gender-specific effects. Human BD1 is down-regulated in human prostatic and renal carcinomas.

保存条件:
       -20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以首次配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项:
       由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
       本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。
       为了您的安全和健康，请穿实验服并戴一次性手套操作。
