Guinea Pig-Raised Antibodies: Antibodies raised in guinea pig can be used with any non-guinea pig second species antibodies (e.g. antibodies raised in mouse, rabbit, goat, etc.) in complex immunostaining or immunoprecipitation protocols. Our line of guinea pig raised antibodies can be combined with any of our rabbit-raised or ATTO-conjugated antibodies in complex immunostaining protocols.
Changes in the cytoplasm free Ca2+ concentration [Ca2+]in regulate a large number of relevant physiological processes and have a major impact on cell development and function. The identification of STIM, the endoplasmic reticulum (ER) Ca2+ sensor, and Orai, a key subunit of the Ca2+ release-activated Ca2+ (CRAC) channel pore, have provided the tools to illuminate the mechanisms of CRAC channel regulation, that play an important role in modulation of the free Ca2+ concentration in non-excitable cells. Store-operated Ca2+ entry (SOCE) is a common and ubiquitous mechanism for regulating Ca2+ influx into cells and is widely expressed in most tissues.
