Human BRAK/CXCL14/重组人胸肾表达趋化因子
产品编号:100-139
产品规格:20μg
Description: Breast and Kidney-expressed chemokine (BRAK) is a CXC chemokine expressed in normal tissue in the absence of inflammatory stimuli, and infrequently expressed in cancer cell lines. BRAK is known to be a highly selective monocyte chemoattractant. However, main function and receptor selectivity is unknown at this time. BRAK contains the four highly conserved cysteine residues present in CXC chemokines. The sequence of the mature protein consists of 87 amino acid residues, and is approximately 30% homologous to the sequences of MIP-2 alpha and beta. Recombinant human BRAK is a 9.4 kDa protein containing 77 amino acid residues.
Source: E. coli
Molecular Weight: 9.4 kDa
Purity: > 98% by SDS-PAGE and HPLC analysis
Endotoxin level/内毒素水平: < 0.1 ng per μg of BRAK
Stabilizer: none
Formulation: lyophilized
Biological Activity: Determined by it's ability to chemoattract activated monocytes using a concentration range of 1.0-10.0 ng/ml.
Reconstitution: The human BRAK should be reconstituted in water to a concentration of 0.1-1.0 mg/ml. This solution can be diluted in water or other buffer solutions or stored at -20°C.
Stability: The lyophilized protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted BRAK is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. Avoid repeated freeze-thaw cycles.
Usage: Human BRAK offered for research use. Not for drug use. Not for human use.
