{"product_id":"cdkn1a-antibody-sc-f0170","title":"p21 Waf1\/Cip1 Antibody","description":"\u003ch2\u003eAbout the Target\u003c\/h2\u003e\u003cp\u003eCDKN1A is a target of interest in many antibody-based workflows. Protein p21 (Cip1\/Waf1) is a cyclin-dependent kinase inhibitor that belongs to the CIP\/Kip family of CDK inhibitors (CKIs). Based on the localization, the p21(Cip1\/Waf1) protein executes various functions in the cell. In the nucleus, p21 (Cip1\/Waf1) binds to and inhibit the activity of CDK1 and CDK2, thereby blocks the transition from the G1 phase to the S phase or from the G2 phase to mitosis following DNA damage, facilitating DNA repair processes. Depending on the literature source, CDKN1A may also be discussed as p21 Waf1\/Cip1 and p21.\u003c\/p\u003e\u003cp\u003eReported cellular context includes cytoplasm and nucleus, which can matter when signal is compared across treatments or changing cell states. Following CDKN1A across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.\u003c\/p\u003e\u003ch2\u003eResearch Context\u003c\/h2\u003e\u003cp\u003eCDKN1A is commonly interpreted in the context of cancer, dna damage \/ repair, and cell cycle research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytoplasm and nucleus, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.\u003c\/p\u003e\u003cp\u003eConsider these angles when interpreting target-level changes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eapparent redistribution between cytoplasm and nucleus across matched conditions\u003c\/li\u003e\n\u003cli\u003echanges associated with proliferative state, oncogenic signaling, or treatment response\u003c\/li\u003e\n\u003cli\u003estress-induced changes after checkpoint activation or genotoxic challenge\u003c\/li\u003e\n\u003cli\u003ecell-cycle linked differences in abundance, timing, or compartmental enrichment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eVariant Considerations\u003c\/h2\u003e\u003cp\u003eIf your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for CDKN1A. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.\u003c\/p\u003e\u003cp\u003eStandardize sampling time, control choice, and downstream analysis thresholds so apparent differences in CDKN1A reflect biology rather than handling. When interpreting CDKN1A, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.\u003c\/p\u003e\u003cp\u003eFor multi-run studies, a shared reference condition can keep CDKN1A trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.\u003c\/p\u003e","brand":"Selleck Chemicals","offers":[{"title":"20 µl","offer_id":57577418621273,"sku":"F0170-20UL","price":139.0,"currency_code":"EUR","in_stock":true},{"title":"100 µl","offer_id":57577418654041,"sku":"F0170-100UL","price":329.0,"currency_code":"EUR","in_stock":true},{"title":"2 × 100 µl","offer_id":57577418686809,"sku":"F0170-2X100UL","price":489.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/1011\/0553\/files\/F0170-IF.png?v=1773598174","url":"https:\/\/absource-diagnostics.myshopify.com\/products\/cdkn1a-antibody-sc-f0170","provider":"Absource Diagnostics","version":"1.0","type":"link"}
