One vial containing lyophilized recombinant human Fractalkine, LIF, TNFβ, VEGF-D, I-TAC, MIP-1α, MIP-1β, and TIM-1.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human TIM-1/KIM-1/HAVCR.  Can be multiplexed with other analytes in Human Group 3.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

T-cell immunoglobulin and mucin domain 1 (TIM-1), also known as Hepatitis A virus cellular receptor 1 (HAVcr-1), is a protein that in humans is encoded by the HAVCR1 gene. The hepatitis A virus cellular receptor 1 is a member of the TIM (T cell transmembrane, immunoglobulin, and mucin) gene family, which plays critical roles in regulating immune cell activity especially regarding the host response to viral infection. TIM-1 is also involved in allergic response, asthma, and transplant tolerance. Members of the TIM gene family including TIM-1 participate in host immune response. The mouse TIM gene family contains eight members (TIM-1-8) while only three TIM genes (TIM-1, TIM-3, and TIM-4) have been identified in humans. TIM-1 is preferentially expressed on Th2 cells and has been identified as a stimulatory molecule for T-cell activation. TIM-1 has been identified as the cellular receptor of hepatitis A virus (HAV). The mucin domain and IgV domain were critical for virus uncoating and infectivity. By using an expression cloning library, IgA has been demonstrated as a specific ligand of TIM-1. The association of TIM-1 and IgA was able to enhance the virus-receptor interaction. Diseases associated with HAVCR1 include atopy and hepatitis.
