簡單介紹：

重組人類趨化因子樣蛋白TAFA-2蛋白與其它公司提供的重組蛋白不同，rHuTAFA-2蛋白產(chǎn)品為采用CFS的無細(xì)胞麥胚蛋白合成系統(tǒng)表達出來的重組蛋白，可表達出對細(xì)胞有毒性、易被蛋白酶降解的蛋白；并獲得具有良好的可溶性，并有翻譯后修飾、從而部分具有功能的蛋白.同時獨有的全自動蛋白純化技術(shù)則簡便高效，將蛋白純化過程中對蛋白的損傷降低到*小程度.重組人類趨化因子樣蛋白TAFA-2蛋白（全長序列）產(chǎn)品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

詳情介紹：

重組人類趨化因子樣蛋白TAFA-2蛋白

Synonyms FAM19A2

Species Human

Accession Q8N3H0

GeneID 338811

Source 重組人類趨化因子樣蛋白TAFA-2蛋白Escherichia coli.

Molecular Weight Approximately 11.2 kDa, a single, non-glycosylated polypeptide chain containing 101 amino acids.

Quantity 5μg/20μg/1000μg

AA Sequence ANHHKAHHVK TGTCEVVALH RCCNKNKIEE RSQTVKCSCF PGQVAGTTRA APSCVDASIV EQKWWCHMQP CLEGEECKVL PDRKGWSCSS GNKVKTTRVT H

Purity > 95 % by SDS-PAGE and HPLC analyses.

Biological Activity 重組人類趨化因子樣蛋白TAFA-2蛋白Fully biologically active when compared to standard. The biological activity is determined by its ability to enhance neurite outgrowth of E16-E18 rat embryonic cortical neurons. rHuTAFA-2, immobilized at 6-24 μg/mL on a 96 well plate, is able to significantly enhance neurite outgrowth.

Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation Lyophilized from a 0.2 μm filtered concentrated solution in 2 × PBS, pH 7.4.

Endotoxin Less than 1 EU/μg of rHuTAFA-2 as determined by LAL method.

Reconstitution 重組人類趨化因子樣蛋白TAFA-2蛋白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 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

Storage 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.

Background TAFA-2 also named FAM19A2, is a chemokine-like protein which is belonged to the FAM19/TAFA family. The family is a newly discovered and distantly related to MIP-1α. It contains 5 members and TAFA proteins are highly expressed in specific brain regions. Like other members of the TAFA family, with the exception of TAFA5, mature TAFA1 contains 10 regularly spaced cysteine residues. Human TAFA2 is 97 % a.a. identical to mouse TAFA2. The biological functions of TAFA family members remain to be determined, but they are postulated to act as brain-specific chemokines or neurokines that take parts in regulators of immune and nervous cells.
