    • Function

      Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1H gives rise to T-type calcium currents. T-type calcium channels belong to the "low-voltage activated (LVA)" group and are strongly blocked by nickel and mibefradil. A particularity of this type of channels is an opening at quite negative potentials, and a voltage-dependent inactivation. T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle. They may also be involved in the modulation of firing patterns of neurons which is important for information processing as well as in cell growth processes.
    • Tissue specificity

      Expressed in kidney, liver, heart, brain. Isoform 2 seems to be testis-specific.
    • Involvement in disease

      Defects in CACNA1H are a cause of susceptibility to idiopathic generalized epilepsy type 6 (IGE6) [MIM:611942]. IGE is characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. IGE6 is a polygenic and multifactorial disease.
    • Sequence similarities

      Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family. CACNA1H subfamily.
    • Domain

      Each of the four internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position.
    • Post-translational

      In response to raising of intracellular calcium, the T-type channels are activated by CaM-kinase II.

    • Immunohistochemical analysis of frozen Human brain tissue sections staining CACNA1H. Samples were fixed with 10% Formalin solution and incubated with primary antibody at 1:1000 dilution for 1 hour at room temperature. A biotinylated goat anti-mouse was used as the secondary antibody. Mayer Hematoxylin was used as a nuclear stain.

    Thank you for your email. I am sorry to hear that you have been experiencing problems with this antibody.

    I have read the details you have kindly provided and have following further questions for better understanding of the problem;

    - Have you used correct filters? The ab150079 absorption maxima is 650 nm while for FITC (ab98692) it is 495.
    - Were the cells permeabilized?
    - Is the sequence of insert protein is interpreted. It may well be that the insert sequence is missing which ab128251 binds.
    The antibodies ab128251 and a84815 are raised against different part of the immunogen.
    - Have you tried optimizing the results by incubating the antibody overnight or by increasing the concentration?

    In order for checking the quality of ab150079 you may put a small drop of ab on slide and then seeing it under microscope. If it emits red colour then conjugate is fine and the problem may be with other steps. If it's not then problem is with secondary antibody.

    It will be very helpful if you could provide the protcol followed step by step.

    Please note that flow cytometry is not a tested application for ab128251 so the Abreview guarantee will not be valid. However if this antibody fails in ELISA, WB and ICC/IF then guarantee will apply as normal product.

    Thank you very much for your cooperation. I will look forward to hearing from you soon.

    Thank you for contacting us and your interest in our products.

    Both the goat polyclonal anti-mouse IgG (ab97239 and ab98692) should be compatible with the mouse anti-CACNA1H antibody (ab84815) for the experiment you hope to perform. The antibody ab98692 is provided pre-adsorbed. This can be very useful when using multi-color imaging and IHC experiments when several primary antibodies and their corresponding secondary antibodies are used simultaneously. It also reduces the risk of cross-reactivity between the secondary antibody and endogenous immunoglobulins present on cell and tissue samples. It can therefore help to reduce non-specific staining.

    I hope this information has been of help. If you have any further questions, please do not hesitate to ask.
