    Characteristics
    • Made in Germany - from design to production - by highly experienced protein experts.
    • Mouse Sh2d1b Protein (raised in Insect Cells) purified by multi-step, protein-specific process to ensure crystallization grade.
    • State-of-the-art algorithm used for plasmid design (Gene synthesis).

    This protein is a made to order protein and will be made for the first time for your order. Our experts in the lab will ensure that you receive a correctly folded protein.

    The big advantage of ordering our made-to-order proteins in comparison to ordering custom made proteins from other companies is that there is no financial obligation in case the protein cannot be expressed or purified.

    In the unlikely event that the protein cannot be expressed or purified we do not charge anything (other companies might charge you for any performed steps in the expression process for custom-made proteins, e.g. fees might apply for the expression plasmid, the first expression experiments or purification optimization).

    When you order this made-to-order protein you will only pay upon receival of the correctly folded protein. With no financial risk on your end you can rest assured that our experienced protein experts will do everything to make sure that you receive the protein you ordered.

    The concentration of our recombinant proteins is measured using the absorbance at 280nm. The protein's absorbance will be measured in several dilutions and is measured against its specific reference buffer.

    The concentration of the protein is calculated using its specific absorption coefficient. We use the Expasy's protparam tool to determine the absorption coefficient of each protein.

    Purification
    Two step purification of proteins expressed in baculovirus infected SF9 insect cells:
    1. In a first purification step, the protein is purified from the cleared cell lysate using three different His-tag capture materials: high yield, EDTA resistant, or DTT resistant. Eluate fractions are analyzed by SDS-PAGE.
    2. Protein containing fractions of the best purification are subjected to second purification step through size exclusion chromatography. Eluate fractions are analyzed by SDS-PAGE and Western blot.
    Purity
    >95 % as determined by SDS PAGE, Size Exclusion Chromatography and Western Blot.
    Sterility
    0.22 μm filtered
    Endotoxin Level
    Protein is endotoxin free.
    Grade

  • Application Notes
    In addition to the applications listed above we expect the protein to work for functional studies as well. As the protein has not been tested for functional studies yet we cannot offer a gurantee though.
    Comment

    Protein has not been tested for activity yet. In cases in which it is highly likely that the recombinant protein with the default tag will be insoluble our protein lab may suggest a higher molecular weight tag (e.g. GST-tag) instead to increase solubility. We will discuss all possible options with you in detail to assure that you receive your protein of interest.

    Background
    Cytoplasmic adapter regulating receptors of the signaling lymphocytic activation molecule (SLAM) family such as CD84, SLAMF1, LY9 and CD244. In SLAM signaling seems to cooperate with SH2D1A/SAP. Plays a role in regulation of effector functions of natural killer (NK) cells by controlling signal transduction through CD244/2B4. However, conflicting results are reported which may reflect the use of different strain backgrounds. Proposed to act as an inhibitor of CD244-mediated NK cell function including cytotoxicity and IFN-gamma production, the latter found also by triggering KLRA4 and KLRK1 next to CD244 (PubMed:16127454). Seems to positively regulate CD244- and CD84-dependent NK cell functions implicating CD244-mediated phosphorylation of VAV1. Activation of SLAMF7-mediated NK cell function does not effect receptor tyrosine phosphorylation but distal signaling (PubMed:19151721, PubMed:20962259, PubMed:24687958). In the context of NK cell-mediated cytotoxicity does not enhance conjugate formation with target cells but stimulates polarization of the microtubule-organizing center and cytotoxic granules toward the NK cell synapse (PubMed:24687958). Negatively regulates CD40-induced cytokine procuction in dendritic cells downstream of SLAM family receptors probably by inducing activation of the PI3K pathway to inhibit p38 MAPK and JNK activation (PubMed:26432891). {ECO:0000250|UniProtKB:O14796, ECO:0000269|PubMed:16127454, ECO:0000269|PubMed:19151721, ECO:0000269|PubMed:20962259, ECO:0000269|PubMed:24687958, ECO:0000269|PubMed:26432891}.
