稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
运输条件
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
PARP1 (Poly(ADP-ribose) polymerase 1) is a critical enzyme involved in the cellular response to DNA damage and plays a significant role in various cellular processes, including DNA repair, genomic stability, and programmed cell death. Its primary function is to detect DNA strand breaks and catalyze the transfer of ADP-ribose units from NAD+ to target proteins, thereby facilitating the recruitment of DNA repair factors to damaged sites. The significance of PARP1 has garnered considerable attention due to its implications in cancer biology, where tumors often exploit DNA repair mechanisms for survival and proliferation. Inhibition of PARP1 has emerged as a promising therapeutic strategy, particularly in cancers with homologous recombination deficiencies, such as BRCA1/2-mutated tumors. Studies of PARP1 recombinant proteins have provided insights into the enzyme's structural and functional properties, allowing researchers to better understand its role in DNA damage response pathways. Additionally, these recombinant proteins serve as essential tools for developing PARP inhibitors and evaluating their efficacy and specificity in preclinical models. The ongoing investigation into PARP1 and its interactions with various cellular pathways continues to illuminate its potential as a target for innovative cancer therapies and offers a deeper understanding of the underlying mechanisms of DNA repair and cell survival in malignant contexts.
