Human MIP-1 beta (CCL4) Recombinant
Categories: CCL chemokinesRecombinant Human Cytokines$70.00 – $2,700.00
Description
Accession
P13236
Source
Optimized DNA sequence encoding Human CCL4/MIP-1 beta chain was expressed in Escherichia Coli.
Molecular weight
Native human MIP-1 beta is generated by the proteolytic removal of the signal peptide and propeptide. This molecule has a calculated molecular mass of approximately 8 kDa. Recombinant CCL4/MIP-1 beta is a disulfide-linked homodimeric protein consisting of 69 amino acid residue subunits,and migrates as an approximately 8 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
Determined by its ability to chemoattract human blood monocytes using a concentration range of.0-10.0 ng/ml.

Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant MIP-1 beta was lyophilized from a 0.2 μm filtered PBS solution.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers
Storage
The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at2° -8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage
This cytokine product is for research purposes only.It may not be used for therapeutics or diagnostic purposes.

Methods
ELISA confirms CBMC antiviral chemokine release following antibody-enhanced dengue virus infection or polyI:C exposure.
- After 24 hours, cell supernatants were harvested and measured for CCL4, CCL5 and CXCL10 by ELISA.
(A) Relative quantification of chemokine mRNA expression to GUS and IPO8 by tissue type.
- Western blots probing for CCL3, CCL4 and GUS in eight samples of CRC with matched distal colon of standard protein concentration (2 mg BSA per ml).
