Applicable Applications for LAG 1 active protein
User optimized
Protein Type
Recombinant
Biological Significance
LAG-1 is CC chemokine that signals through the CCR5 receptor. LAG-1 is identical to MIP-1beta (ACT II isotype) except for two amino acid substitutions; arginine for histidine at position 22 and serine for glycine at position 47 of the mature protein. LAG-1 chemoattracts monocytes, and exhibits activity as an HIV suppressive factor.
Bioactivity
Determined by it's ability to chemoattract CCR5 transfected cells using a concentration of 0.1-10.0 ng/ml
Endotoxin Levels
Endotoxin level is less than 0.1 ng per ug (1 EU/ug).
Expression System
E Coli
Preparation and Storage
Store at 4 degree C until reconstitution. Following reconstitution aliquot and freeze at -20 degree C for long term storage. Avoid repeated freeze/thaw cycles.

NCBI Description

The protein encoded by this gene is a mitogen-inducible monokine and is one of the major HIV-suppressive factors produced by CD8+ T-cells. The encoded protein is secreted and has chemokinetic and inflammatory functions. [provided by RefSeq, Dec 2012]

Uniprot Description

CCL4: Monokine with inflammatory and chemokinetic properties. Binds to CCR5. One of the major HIV-suppressive factors produced by CD8+ T-cells. Recombinant MIP-1-beta induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). The processed form MIP-1-beta(3-69) retains the abilities to induce down-modulation of surface expression of the chemokine receptor CCR5 and to inhibit the CCR5- mediated entry of HIV-1 in T-cells. MIP-1-beta(3-69) is also a ligand for CCR1 and CCR2 isoform B. Belongs to the intercrine beta (chemokine CC) family.

Product Notes

The LAG 1 ccl4 (Catalog #AAA539438) is an Active Protein produced from Human and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's LAG 1 can be used in a range of immunoassay formats including, but not limited to, User optimized. Researchers should empirically determine the suitability of the LAG 1 ccl4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Region of LAG 1 protein correspond ing to amino acids APMGSDPPTA CCFSYTARKL PRNFVVDYYE TSSLCSQPAV VFQTKRSKQV CADPSESWVQ EYVYDLELN. It is sometimes possible for the material contained within the vial of "LAG 1, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
