Product Overview

Description	Recombinant Human Carcinoembryonic Antigen-Related Cell Adhesion Molecule 8 is produced by our Mammalian expression system and the target gene encoding Gln35-His141 is expressed with a 6His tag at the C-terminus.
Accession	P31997
Synonym	Carcinoembryonic Antigen-Related Cell Adhesion Molecule 8; CD67 Antigen; Carcinoembryonic Antigen CGM6; Non-Specific Cross-Reacting Antigen NCA-95; CD66b; CEACAM8; CGM6
Gene Background	Carcinoembryonic Antigen-Related Cell Adhesion Molecule 8 (CEACAM8) is a single chain, GPI-anchored, highly glycosylated protein which belongs to the immunoglobulin superfamily and the carcinoembryonic antigen(CEA) family. CEACAM8 is expressed by neutrophils and eosinophils, and serves as a binding partner for CEACAM-6 and Galectin-3. It contains two Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. Mature human CEACAM8 is a 287 amino acid GPI-linked glycoprotein. CEACAM family members are a set of widely expressed proteins involved in several biological functions, including cell adhesion, migration, signal transduction, and the regulation of gene expression. Abnormal overexpression and downregulation of some CEACAMs have been described in tumor cells.
Molecular Mass	13.03 KDa
Apmol Mass	17-25 KDa, reducing conditions
Formulation	Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
Endotoxin	Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity	Greater than 95% as determined by reducing SDS-PAGE. (QC verified)
Biological Activity	Not tested
Reconstitution	Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Storage	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.
Shipping	The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
Usage	For Research Use Only

Target Details

Target Function	Cell surface glycoprotein that plays a role in cell adhesion in a calcium-independent manner. Mediates heterophilic cell adhesion with other carcinoembryonic antigen-related cell adhesion molecules, such as CEACAM6. Heterophilic interaction with CEACAM8 occurs in activated neutrophils.
Subcellular Location	Cell membrane; Lipid-anchor, GPI-anchor. Cell surface.
Protein Families	Immunoglobulin superfamily, CEA family
Database References	HGNC: 1820 OMIM: 615747 KEGG: hsa:1088 STRING: 9606.ENSP00000244336 UniGene: Hs.41
Tissue Specificity	Expressed in leukocytes of chronic myeloid Leukemia patients and bone marrow.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
