中文名称: Recombinant Human B-Defensin 4A
规格: 10ug ; 50ug ; 500ug ; 1mg
外观(性状)： Lyophilized from a 0.2 μm filtered solution ofPBS, pH7.4.
纯度: ≥95% as determined by reducing SDS-PAGE.
储存条件: Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.

背景说明： β-Defensin 4A is a membrane-active cationic peptide that functions in inflammation and innate immune responses.There are at least 30 β-Defensins，which are distinguished from α-Defensins by the connectivity pattern of their three intermolecular disulfide bonds.Members of the Defensin family are highly similar in protein sequence.This gene encodes Defensin，DEFB4;，which has broad-spectrum antimicrobial activity and may play an important role in innate epithelial defense.They are highly expressed in skin and tonsils，and to a lesser extent in trachea，uterus，kidney，thymus，adenoid，pharynx and tongue.β-Defensin 4A has low expression in salivary gland，bone marrow，colon，stomach，polyp and larynx.No expression in small intestine.The 45 amino acid mature human BD3 shares 38% and 33% amino acid sequence identity with mouse and rat BD3，respectively.

溶剂: Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
内毒素: Less than 0.1 ng/ug(1 EU/ug)as determined by LAL test.
